In recent years, the computational fluid dynamics has been widely used in the aviation, weather and chemical industry and so on. The demand on computing power for modern computational fluid dynamics is getting higher and higher. Aiming at the features of the LBM (Lattice Boltzmann Method), the authors put forward a parallel data structure layout of the D2Q9 model and related algorithm based on CUDA (Compute Unified Device Architecture).Taking the plane Poiseuille flow as a test example, they implement the parallel computation of the LBM based on LBGK (Lattice Bhatnagar-Gross-Krook) model on GPU (Graphic Processing Unit).
