Large eddy simulation of turbulent flow in a three-way section using lattice Boltzmann method

چکیده مقاله

The Lattice Boltzmann Method (LBM) is a novel method for simulating convection-diffusion type of problems. It has direct advantage over other available methods. One advantage of LBM is that it can be easily parallelized and hence can be used to simulate fluid flow in multi-core computers using parallel computing. In this work we have used the Lattice Boltzmann method to simulate turbulent flow in a three-way section using the Smagorinsky–Lilly SGS model for Large Eddy Simuation (LES). LES is widely used in simulating turbulent flows in industries because of its less computational needs compared to Direct Numerical Simulation (DNS) where the Kolmogorov Eddies have to be resolved. The LBM results are validated against those available in the literature and there is excellent agreement between them.
