Abstract:
The paper describes an implementation of the conservative projection method
for solving the Boltzmann equation on GPU. The NVidia CUDA technology is used
as a computational platform. Methods for an optimal implementation of a solver
for two-dimensional geometry and methods for setting boundary conditions,
implementation of the geometry, and storage of integrating grids are developed.
The developed approach is used to perform computations for the problem of slow
gas flow in a rectangular cavity and the problem of shock wave propagation in
a narrow channel. The efficiency of using GPU for the analysis of slow and
high-speed flows of rarefied gas is shown.
Keywords:
GPU; CUDA; massively-parallel computation; Boltzmann equation; rarefied gas.
