Abstract

This article introduces a numerical scheme to simulate water impact on rigid structures, in which the air-water two phase flow is solved using the pressure-based Computational Fluid Dynamics method. This method is implemented using an in-house code, the General Transport Equation Analyser, which is an unstructured grid finite volume solver. The performance of the PC is greatly developed, so as expected the network can provide great computational capability. Based on this point, we developed a data structure system and parallel code. Two simple test cases have been done with the program and reasonable results were obtained. The air cushion has a great effect on the peak pressure of the impact process, while the impulse is almost constant with different air densities. Air density also influences the free surface distribution, which causes different flow characteristics.

Water droplet freezing on cold surfaces with distinct wetabilities
Article

  • May 2021
  • HEAT MASS TRANSFER
This paper investigates the total freezing time of droplets on surfaces with various wettabilities with horizontal and inclined orientations. A two-dimensional Volume of Fluid (VOF) method was applied to capture the liquid-air interface, and an automatic localized grid treatment technique was applied to increase the accuracy, especially near the impact and spreading areas. The Kistler and Shikhumurzaev dynamic contact angle models were implemented to impose the dynamic contact angles on different surfaces. An enthalpy-porosity technique was used to predict the phase change of droplets after impact with the surface. The results of the nondimensional droplet diameter ratios and total freezing times for both dynamic contact angle models have been presented and verified with experimental data. The effects of both wetting properties and the surface inclination on the freezing time have been analyzed. The results indicate that a lower surface temperature, a decrease in static contact angle and a higher inclination will result in more rapid freezing of droplets.

... The following assumptions are maintained to apply the multiphase flow model: (a) the droplets in the dispersed phase are equally dispersed in the continuous phase; (b) the interpenetration between oil and water is ignored, which means oil and water are immiscible with each other; (c) all phases are incompressible; (d) density and viscosity are both constant in the calculation domain; and (e) no backward flow in the oil and water outlet, which means the gauge pressure at the outlet is zero. The VOF model, which is designed for two or more immiscible fluids, is utilized for modeling the motion of the continuous phase and the discrete phase motion [20][21][22][23]. In this paper, the water is maintained as a continuous phase. ...
Separation dynamics of immiscible liquids
Article
Full-text available
  • Dec 2020
In this paper, the geometric design of a gravity-based separator is studied with a computational fluid dynamics method. ANSYS Fluent (18.2) is used to model the ratio of horizontal and vertical lengths with three dimensionless groups. A dimensional analysis method is used to develop a new correlation of separator geometric design. Corresponding plots were created and analyzed using nonlinear regression on the x–y Cartesian coordinate system. Also, manual iterations were performed to determine the coefficients in the general correlation relationship. The dimensional analysis results show that the Reynolds and Euler numbers have a direct correlation with separator design, which means increasing the Reynolds and Euler numbers require a separator with a larger length to height ratio to achieve the same separation efficiency. However, the Weber number has an inverse correlation with separator design, which means an increase in the Weber number requires a separator with a smaller length to height ratio. The new correlation developed in this paper can be used as a reference for separator geometry design to separate immiscible fluids with a wide range of fluid properties.

Three-Dimensional Numerical and Experimental Simulation of Wave Run-Up Due to Wave Impact With a Vertical Surface
Article
  • Feb 2018
This paper describes a numerical simulation of the interaction of a single nonlinear wave with a solid vertical surface in three dimensions. A coupled volume of fluid (VOF) and level set method (LSM) is used to simulate the wave-body interaction. A Cartesian-grid method is used to model immersed solid boundaries with constant grid spacing for simplicity and lower storage requirements. Mesh refinement is implemented near the wall boundaries due to the complex behavior of the free surface around the body. The behavior of the wave impact, the water sheet, and the high-speed jet arising from the wave impact are all captured with these methods. The numerical scheme is implemented using parallel computing due to the high central processing unit and memory requirements of this simulation. The maximum wave run-up velocity, instant wave run-up velocity in front of the vertical surface, the sheet break-up length, and the maximum impact pressure are computed for several input wave characteristics. Results are compared with a laboratory experiment that was carried out in a tow tank in which several generated waves were impacted with a fixed flat-shaped plate model. The numerical and experimental data on sheet breakup length are further compared with an analytical linear stability model for a viscous liquid sheet, and good agreement is achieved. The comparison between the numerical model and the experimental measurements of pressure, the wave run-up velocity, and the break-up length in front of the plate model shows good agreement.

Recent Advances in Liquid Sloshing Dynamics
Article
Full-text available
  • Mar 2001
A liquid free surface in partially filled containers can experience a wide spectrum of motions such as planar, non-planar, rotational, quasi-periodic, chaotic, and disintegration. Civil engineers and seismologists have been studying liquid sloshing effects on large dams, oil tanks and elevated water towers under ground motion. Since the early 1960's, the problem of liquid sloshing dynamics has been of major concern to aerospace engineers studying the influence of liquid propellant sloshing on the flight performance of jet vehicles. Since then, new areas of research activities have emerged. The modern theory of nonlinear dynamics has indeed promoted further studies and uncovered complex nonlinear phenomena. These include rotary sloshing, Faraday waves, nonlinear liquid sloshing interaction with elastic structures, internal resonance effects, stochastic sloshing dynamics, hydrodynamic sloshing impact dynamics, g-jitter under microgravity field, cross-waves, and spatial resonance. The dynamic stability of liquid gas tankers and ship cargo tankers, and liquid hydrodynamic impact loading are problems of current interest to the designers of such systems. This article will address the means of passive control of liquid sloshing and the use of liquid sloshing forces to control vibratory structures. Other important contributions include the development of digital computer codes to solve complex problems that were difficult to handle in the past. The purpose of this article is to review the research work developed in different applications. It will highlight the major achievements and results reported in the literature. Some early work will be cited very briefly in order to provide an updated bibliography of liquid sloshing dynamics. This review article contains 1,319 references.

Parallel CFD algorithm realization based on PC cluster
Article
  • Feb 2007
With developing of computer and numerical technique, computational fluid dynamics becomes an important branch of the fluid dynamics. The CFD technique spreads quickly with an enhancement of the PC performance and becomes a basic tool for industrial design and analysis. But PC still cannot deal with high performance required field such as research on fluid mechanic details and large-scale industrial design computation. A parallel CFD algorithm based on the PC cluster and Message Passing Interface is presented, which can provide great computational capability. A two-node PC cluster system is constructed, and a data structure system and SPMD parallel code with MPI are developed, including auto domain decomposition, and re-index of element and 1-0 modules. A classic backing face step case has been done with the program and reasonable results are obtained. The result is also consistent with the serial one of the dominant commercial CFD software Fluent.

Coupled Analysis of Nonlinear Interaction Between Fluid and Structure during Impact
Article
  • Jan 2000
This paper presents a method for analysing the hydroelastic interaction during the impact of a structure with water. The completely coupled equation for fluid flow and structural response is solved by the boundary element method for the former and by the finite element method for the latter. During the impact, the nonlinear free surface boundary condition is satisfied, including proper treatment of the jet, and the full interaction with the linear elastic structure is taken into account. The convergence of the code is verified by different fluid domain and mesh sizes and different time steps. The accuracy of the code is confirmed by comparing the obtained results with published data. Various examples of a V-shape structure impacting vertically upon water are provided. The numerical result from this coupled analysis shows that the hydroelasticity has different effects on the dynamic response of the body with different deadrise angles, which may have some important implications for structural design.

Numerical simulation of oblique water entry of an asymmetrical wedge
Article
  • Nov 2008
  • OCEAN ENG
The hydrodynamic problem of a two-dimensional asymmetrical wedge entering calm water obliquely at constant speed is analyzed based on the velocity potential theory. The gravity effect on the flow is ignored based on the assumption that the ratio of the entry speed to the acceleration due to gravity is much larger than the time scale of interest. The problem of this similarity flow is solved by a boundary element method together with an analytical solution for the jet based on the shallow water approximation. Various results are provided for the wave elevation, pressure distribution and force at different deadrise angles and at different oblique entry. The effects of asymmetry and horizontal speed on these results are investigated.

Volume of Fluid (VOF) Method for the Dynamics of Free Boundary
Article
  • Jan 1981
Several methods have been previously used to approximate free boundaries in finite-difference numerical simulations. A simple, but powerful, method is described that is based on the concept of a fractional volume of fluid (VOF). This method is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations. To illustrate the method, a description is given for an incompressible hydrodynamics code, SOLA-VOF, that uses the VOF technique to track free fluid surfaces.

Wave Impact on a Wall Using Pressure-Impulse Theory. I: Trapped Air
Article
  • Jul 2000
Often when a plunging breaker impacts on a wall, an air pocket is trapped at the wall. This paper extends a pressure-impulse model for wave impact on a wall to include a simple model of a trapped air pocket. The inclusion of an air pocket leads to a higher impulse at impact for a given wave as there is some rebound of the water. The model is shown to compare satisfactorily with small-scale experimental data performed on a caisson breakwater with an impermeable berm. The effect of a porous berm on pressure impulse is investigated theoretically in a companion paper.

Air cushioning and bubble entrapment in three-dimensional droplet impacts
Article
  • Apr 2010
Droplet deformation by air cushioning prior to impact is considered. A model is presented coupling the free-surface deformation of a droplet with the pressure field in the narrow air layer generated as a droplet approaches an impact. The model is based upon the density and viscosity in the air being small compared with those in the liquid. Additionally, the Reynolds number, defined using the droplet radius ℛ and approach velocity l , is such that lubrication forces dominate in the air layer. In the absence of significant surface tension or compressibility effects, these assumptions lead to coupled nonlinear integro-differential equations describing the evolution of a droplet free surface approaching a solid wall through air, with or without topography. The problem is studied numerically with a boundary-element method in the inviscid droplet coupled with a finite-difference method in the lubricating air. In normal impacts, air cushioning will be shown to deflect the free surface upwards, delaying the moment of touchdown and trapping a bubble. The volume of the bubble is found to be (μ g 4/3 ℛ 5/3 /ρ l 4/3 l 4/3 ) , where μ g is the gas viscosity and ρ l is the liquid density and the numerically computed pre-factor = 94.48. Bubble volumes predicted by this relationship are shown to be in good agreement with experimental observations. In oblique impact or impact with a moving surface with sufficient horizontal motion a bubble is not trapped beneath the approaching droplet. In this case, the region of touchdown is initially crescent shaped with air effects accelerating the moment of touchdown.

Asymptotic theory of liquid-solid impact
Article
The liquid-solid impact problem is analysed with the help of the method of matched asymptotic expansions. This method allows us to estimate the roles of different effects (viscosity of the liquid, surface tension, compressibility, nonlinearity, geometry) on the impact, to distinguish the regions of the flow and the stages of the impact, where and when each of these effects is of major significance, to present a complete picture of the flow, and describe approximately such phenomena as jetting, escape of the shock onto the liquid-free surface and cavitation. Five stages of the impact are distinguished: supersonic stage, transonic stage, subsonic stage, inertia stage and the stage of developed liquid flow. The asymptotic analysis of each stage is based on general principles of hydrodynamics and will be helpful to design experiments on liquid impact and to develop an adequate computational algorithm, as well as to understand the dynamics of the process.
