Abstract

Results of the decision of the Riman problems on border inert gas - a gas mixture are resulted. As inert gas helium, as a gas mixture - the hydrogen- oxygen explosion mixture diluted with argon was considered. The problem dared in «frozen», «equilibrium» and «nonequilibrium» statements. It is received that the parameters of the stationary recompressed detonation wave received in non-stationary nonequilibrium statement coincide with the corresponding parameters received at the decision of an automodelling problem about disintegration of rupture in «equilibrium» statement.

Keywords:

the numerical simulation, problem of Riman, explosive mixter, the recompressed detonation wave, equilibrium detonation adiabatic curve, chemical reaction.
