Abstract: The numerical results obtained when solving the two- and three-dimensional gas dynamics problems with consideration of chemical kinetics equations are discussed. The solution of gas-dynamic equations is performed with schemes like TVD (Total Variation Diminishing) on a hybrid system comprising of central processing units and graphics accelerators. The calculations show a good parallelization of gas dynamics problems and chemical kinetics problems on computing systems with graphics coprocessors.

Keywords: computational fluid dynamics; CFD; mathematical modeling; gas dynamics; chemical kinetics; graphics accelerators; GPU.
