Lattice Boltzman Simulations of Cavity Flow Using CUDA

Abstract:

GPGPU has drawn much attention on accelerating non-graphic applications.A new algorithm on the numerical simulation of Lattice-Boltzmann method (LBM) based on CUDA is studied.The cavity flow is simulated by D2Q9 model of LBM method ,with the non-equilibrium extrapolation method for velocity boundary to deal the wall boundary conditions and using global memory and texture memory to store data.In the model the 9 distribution functions were all stored in the form of two-dimensional grid, each grid is assigned a thread and each thread block includes 256 threads.The simulation for cavity flow with LBM was carried out by CUDA and NVIDIA GeForce 8600 GT on a PC.The speed is more than 15 times faster than that of the CPU.
