MODELING OF NONSTATIONARY FLOW IN THE RAMJET CHANNEL WITH A DISTRIBUTED PULSE-PERIODIC ENERGY SUPPLY
V. P. Zamuraev and A. P. Kalinina UDC 533.6.011 A study has been made of the influence of a pulse-periodic supply of energy that is equal to the energy released in combustion of hydrogen in air on the structure of supersonic flow in a channel of variable cross section, which models the ramjet duct. The flow has been modeled based on two-dimensional nonstationary gas-dynamics equations. Different regimes of flow depending on the configuration of the zones of energy supply and the excess-air coefficient have been obtained.
