Transition is the basic phenomena of complex flow regime changes in fluid mechanics. So far, axiomatic expression and rigorous mathematical description transition separation are important scientific problems, which also great significance to development Applied Science. This article obtaining conditions general for through excited state theory flowfield, derivation based on N-S equations, combi...

This paper develops a computational fluid dynamics capability for simulating the radiative emission from meteor shock-layer and wake to an external observer. The developed includes impact of radiation ablation on flowfield, where coupled accounts flowfield energy equations injection species meteoroid surface into flow. updated chemistry nonequilibrium models, which are compiled literature. To p...

A numerical simulation of the gas-dynamic processes in thrust vectorable nozzle solid rocket motor is considered. Construction a geometric model and generation computational mesh, reconstruction mesh at each time step are discussed. Calculations flowfield combustion products pre-nozzle chamber block carried out for various angles rotation. The distributions gas dynamic quantities volume corresp...
