Color in Healthcare Environments

Abstract

The paper describes the implementation of conservative projection method of solving the Boltzmann equation on GPU. The NVIDIA CUDA technology is used as the computational platform. Methods for optimal implementation of the solver for two-dimensional geometry and methods for setting boundary conditions, implementation of the geometry and storage of integrating grids were developed. The developed methodology was used to perform calculations for the problem of slow gas flow in a rectangular cavity and that of shock wave propagation in a narrow channel. The efficiency of using GPU for analysis of slow and high-speed flows of rarefied gas is demonstrated.
