Conference Paper
به دست آوردن جواب تحلیلی برخی از معادلات دیفرانسیل جزئی غیرخطی، مگر در شرایط خاص امکان‌پذیر نمی‌باشد که این‌گونه معادلات را می‌توان با روش‌های عددی حل نمود. معادله‌ مورد نظر در این تحقیق، معادله برگر در حالت دو بعدی وابسته به زمان است که پدیده سرعت سقوط ذره درون سیال نزدیک به سکون مانند آب رسوب دار پشت یک سد را مدل می‌کند. در این تحقیق برای حل معاد...

In this paper, at first by means of the differential quadrature element-incremental method as a computationally efficient and accurate numerical tool in conjunction with the Newton-Raphson method, the behaviour of the bicomponent fixed-bed adsorption is studied. The kinetics of the adsorption is formulated based on the linear driving force (LDF) ap...
Article
An inverse algorithm to estimate the adsorption kinetics inside the spherical particles in a constant molar flow (CMF) gas adsorber reservoir by measuring the bulk pressure is developed. The formulation includes Knudsen diffusion, surface diffusion, slip and viscous flows. To obtain an efficient algorithm, the conjugate gradient method (CGM) for op...

As a first step to analyze the inverse kinetic of adsorption, an inverse algorithm is developed to estimate equilibrium adsorption isotherm in a gas storage vessel by using the dynamic transient internal pressure. In the present study, no prior information is need for the functional form of the unknown isotherm equation to solve continuity equation...
Article
High-molecular-weight hydrocarbons and asphaltenes are important constituents of petroleum and can cause problems related to crystallization and deposition of asphaltene. This article introduces an extension of the cubic equation of state (Peng-Robinson EOS) to describe asphaltene–toluene mixture vapor–liquid equilibria (VLE) and characterize pure...
Article
A two-dimensional inverse transient heat conduction algorithm is developed to estimate the heat flux and convection heat transfer coefficient on the bottom (top) surface of the multilayered functionally graded (FG) circular plates using the measured temperature on their top (bottom) surface. The non-Fourier heat transfer, in conjunction with the la...
Article
Inverse transient heat conduction problems of a multilayered functionally graded (FG) cylinder are presented. The approach is based on measurement of temperature on the outer surface of the cylinder to estimate the heat flux and convection heat transfer coefficient on its inner surface. The non-Fourier heat transfer equation is employed to accurate...

This paper presents a computationally efficient and an accurate methodology in differential quadrature element method (EDQM) analysis of the nonlinear one-dimensional Burgers' equation. Based on this approach, the total spatial and temporal domain is divided into a set of sub-domain and in each sub-domain, the DQ rule is employed to discretize the...
Article
In this work, the heat conduction with finite wave heat speed of multi-layered domain made of functionally graded materials (FGMs) subjected to heat generation is simulated. For this purpose, the domain is divided into a set of mathematical layers, the number of which can be equal or greater than those of the physical layers. Then, in each mathemat...

As a first endeavor, the one- and two-dimensional heat wave propagation in a medium subjected to different boundary conditions and with temperature-dependent thermal conductivity is studied. Both the spatial as well as the temporal domain is discretized using the differential quadrature method (DQM). This results in superior accuracy with fewer deg...

The soil infiltration process is one of the hydrological cycle processes, attracting the attention of the hydrologists more than any other process. This process provides conversion of the raw rainfall into the excessrainfall; and ultimately the excess rainfall is used for describing the rainfall-runoff models. In most of the infiltration models, th...

An optimal control procedure for estimating the heat fluxes on the boundaries of functionally graded (FG) thick plates to reach the desired domain temperature distributions in a specified time interval of heating is presented. The conjugate gradient method (CGM) is employed for optimization, and the differential quadrature method as an accurate and...

The two-dimensional nonlinear transient heat transfer analysis of variable cross section pin-fins is studied using the incremental differential quadrature method (IDQM) as a simple, accurate, and computationally efficient numerical tool. The formulations are general so that it can easily be used for arbitrary continuously varying cross section pin...

The shape optimization of non-symmetric, convective–radiative annular fins is performed based on two-dimensional heat transfer analysis. The formulations are general so that the spatial and temperature dependent geometrical and thermal parameters can easily be implemented. The thermal conductivity of the fin is assumed to vary as a linear function...

An incremental differential quadrature (IDQ) analysis of the two-dimensional nonlinear transient heat transfer analysis of variable section annular fins is presented. The temporal domain is decomposed into a set of sub-domains, and each sub-domain is discretized by using the DQ method. The irregular physical domain of the variable section annular f...

A rapidly converging differential quadrature element method (DQEM) for nonlinear transient heat conduction analysis of extended surfaces is developed. In employing the method, the spatial domain is decomposed into subdomains or elements. At the boundary grid points of any two adjacent elements, boundary conditions and/or compatibility conditions ar...
