Numerical study of a quasi-hydrodynamic system of equations for flow computation at small mach numbers

The applicability of numerical algorithms based on a quasi-hydrodynamic system of equations for computing viscous heat-conducting compressible gas flows at Mach numbers $\mathrm{M}=10^{-2}$–$10^{-1}$ is studied numerically. The numerical algorithm is briefly described, and the results obtained for a number of two- and three-dimensional test problems are presented and compared with earlier numerical data.
