Abstract: In this paper, the single-relaxation time (SRT) lattice Boltzmann method is used to simulate in two-dimension a channel flow around a square obstacle [1-2]. Simulation of such flows requires appropriate boundary conditions. In this work, the bounce-back boundary conditions are applied to the bottom and top walls, at the inlet, conditions of Zou and He [3], however, at the outlet a simple extrapolation is employed [4]. The streamlines are plotted for Reynolds numbers varying from 1 to 2000. The results are compared with those of the literature [5], and the study proves that the SRT-LBM ...
