Abstract

Abstract: The parallel lattice Boltzmann algorithm was used to calculate the flow around twodimensional square cylinder, cylinder, and NACA0012 airfoil. We obtained the flow results at different Reynolds numbers and different time steps. The calculation results show that the parallel algorithm can increase the computational region of flow field.

Key words: parallel computing, drag coefficient, lattice Boltzmann method, flows around twodimensional cylinder
