Hydrocarbon-fueled scramjet is one of the most promising air-breathing propulsion systems for hypersonic flight, but the wall thermal protection issue strictly limits its maximum flight Mach number. This study presents a fuel indirect cooling based thermal management system (TMS) scheme, in...

For hydrocarbon-fueled turbojet engines with a precooling technology, the precooling technology with a low-temperature endothermic fuel is a great potential way to solve the problem of sharp reduction of the specific impulse caused by the insufficient heat sink of the hydrocarbon fuel. To study...

A hypersonic vehicle, its flight state is changeable, which is often related to the heat load change of chamber wall. Thermal and flow response characteristics during flight state change are investigated in this research experimentally by utilizing the electrically heat experiment system. It is...

The insight information of subcooled flow boiling is very important for the development of boiling crisis mechanistic model. In this paper, visual experiment is carried out in a vertical square channel with a heating rod with diameter of 9.5 mm. Based on the near-wall bubble behavior captured by...
