Turbulent Flow Modeling Using Lattice Boltzmann Method

EasyChair Preprint no. 88

4 pagesDate: April 23, 2018


This work is concerning the sudy of turbulent flows arround obstacles in High Reynolds number using LB Method.

At first, a detailed study of computationnal LBM method is presented. The D2Q9 model is used for modeling fluid flow in an horizontal channel. The model is validated by a comparaison between analytical and computationnal velocity profile with poiseuille flow.

At second, the scheme is applied for simulation flows arround square cylinder, turbulence modeling is discuted, an algorithm of Large Eddy Simulation (LES) at high Reynolds number is developped and Smagorinsky model is implemented in LB2D code.

In fact the results were well compared with benchmark solution and with published experimental data.

Keyphrases: CFD, LBM, LES
