Article
Two-way multiple same-level and telescoping grid nesting capabilities are implemented in the Geophysical Fluid Dynamics Laboratory (GFDL)'s Finite-Volume Cubed-Sphere Dynamical Core (FV3). Simulations are performed within GFDL's System for High-resolution modeling for Earth-to-Local Domains (SHiELD) using global and regional multiple nest configura...

Article
A conceptual model for targeted particle delivery is proposed using controlled vortex ring reconnection. Entrained particles can be efficiently transported within the core of vortex rings which advect via self-induction. A pair of these particle-transporting vortex rings traveling in the streamwise direction along parallel trajectories will mutuall...

A conceptual model for targeted particle delivery is proposed using controlled vortex ring reconnection. Entrained particles can be efficiently transported within the core of the vortex ring which is propelled via self-induction. A pair of these particle-transporting vortices travelling in the streamwise direction along parallel trajectories will m...
Article
In gas-solid fluidization highly resolved simulations (HRS) with microscopic two-fluid modeling (mTFM) are frequently employed for deriving sub-grid closures for filtered parameters that are required in filtered formulations useful in large scale simulations of real flows. This work intends to contribute for improving the accuracy of underlying HRS...
Article
Inductively-heated solid particles dispersed within a decaying isotropic turbulent carrier gas are investigated via Direct Numerical Simulations (DNS). The multiphase simulations account for the compressibility and temperature-dependent viscosity effects of the carrier gas. We develop a semi-empirical model for solid particle heating through hyster...

A targeted turbulent flow control strategy, based on selective heating of streamwise-aligned heat strips, is assessed for drag reduction using direct numerical simulations of variable viscosity and compressible turbulent channel flows. As increasing the temperature of a gas increases its viscosity, heating is generally an unfavorable drag mitigatio...
Presentation
Bidimensional empirical mode decomposition (BEMD) is an empirical method to decompose fluctuating signals into various intrinsic mode functions (IMF); these represent different scales of the turbulent fluctuations. The scale separation flow permits an analysis of their respective contributions towards the overall skin friction of the turbulent boun...
Article
Sub‐grid closures for filtered two‐fluid models (fTFM) useful in large scale simulations (LSS) of riser flows can be derived from highly resolved simulations (HRS) with microscopic two‐fluid modeling (mTFM). Accurate sub‐grid closures require accurate mTFM formulations as well as accurate correlation of relevant filtered parameters to suitable inde...
Article
Computing the velocity field magnitude with prescribed velocities on the pressure and suction sides represents the most important step in the inverse design of transonic axial turbomachinery blade profiles. The objective is to develop a numerical method to solve the isentropic velocity field with prescribed velocities at the boundaries. We will pre...
Article
This paper presents a comprehensive experimental work for the application of permanent magnets with the intensity of 9000 Gauss to a four‐stroke four cylinders gasoline engine on fuel lines at a location near to the combustion chamber. By using the permanent magnet, the liquid fuel disintegrates into small diameter, and De‐clustering of the fuel mo...
Article
Sub-grid models for filtered and residual stresses are required as closures in filtered two-fluid modeling of gas-solid fluidized flows. An approach for deriving such models consists of filtering over results from highly resolved simulations with microscopic two-fluid modeling, which are mostly performed under suspension like conditions as separati...

In order to reduce the harmful effect on the environment, using the oxygenated fuels such as biofuel blends as fuel has been on the spotlights for the internal combustion engines. For this rationale; the diesel engine operated with blends of sunflower biodiesel and diesel fuel (blending of 0%, 10%, 20%, and 100% biodiesel fuel with conventional die...
