Numerical algorithm for 3D moderately rarefied gas
flows simulation within domains with voxel geometry
Numerical algorithm based on quasi-hydrodynamic equations for simulation of isothermal viscous gas flows within domains with complex voxel geometry is proposed. Flows with no-slip as well as slip boundary conditions (for moderately rarefied gas flows) are considered. Validity of proposed algorithm is exemplified by numerical solution of several classical hydrodynamic problems.
