Numerical Simulation of Fluid Flow Past a Square Cylinder Using a Lattice Boltzmann Method
The method of lattice boltzmann equation(LBE) is a kinetic-based approach for fluid flow computations. In the last decade, minimal kinetic models, and primarily the LBE, have met with significant success in the simulation of complex hydrodynamic phenomena, ranging from slow flows in grossly irregular geometries to fully developed turbulence, to flow with dynamic phase transitions. In the presen...

15 صفحه اولEvaluation of Detached Eddy Simulation for Turbulent Wake Applications
Simulations of a low-speed square cylinder wake and a supersonic axisymmetric base wake are performed using the Detached Eddy Simulation (DES) model. A reduced-dissipation form of the Symmetric TVD scheme is employed to mitigate the effects of dissipative error in regions of smooth flow. The reduceddissipation scheme is demonstrated on a 2D square cylinder wake problem, showing a marked improve...
متن کاملLarge eddy simulation of unsteady turbulent flow in a semi-industrial size spray dryer
This paper is concerned with the numerical simulation of gas flow inside spray dryers, which is known to be highly transient. Experimental evidence presented in the literature to date is acquired either at a scale much smaller than industrial or at a limited number of locations in the system (e.g. the central axis). Alternatively, computational fluid dynamics (CFD) simulation, in particular met...
متن کاملAIAA 2003–4085 Evaluation of a Second-Order Accurate Navier-Stokes Code for Detached Eddy Simulation Past a Circular Cylinder
We evaluate the applicability of a production computational fluid dynamics code for conducting detached eddy simulation for unsteady flows. A second-order accurate Navier-Stokes code developed at NASA Langley Research Center, known as TLNS3D, is used for these simulations. We focus our attention on high Reynolds number flow (Re = 5× 10 − 1.4× 10) past a circular cylinder to simulate flows with ...
