飞行器持续气动加热的耦合性分析

分析了飞行器持续受热过程中的耦合性，指出了耦合性在分要持续气动加热问题中的必要性。针对存在的耦合性，本文提出了一种处理方法，并在此基础上给出了部分模拟计算结果。这些结果能够定性地反映出耦合性在气动加热问题上的影响。同时指出，任何瞬态算法和技术在评估飞行器持续受热和导热问题时必须十分慎重。

An Analysis of Coupling Feature in Continuing Gasdynamic Heating over Flight Vehicles

The coupling feature exsiting in continuing gasdynamic heating over flight vehicles is analysed. It emphasizes the necessity to account for the coupling in analysing gasdynamic heating problems. A method is developed how to deal with the coupling feature, by which some numerical simulations are made here. The results can, at least qualitatively, depict the coupling effects on gasdynamic heating process. In addition, it is indicated that the usage of any transient techniques, numerical as well as experimental, must be careful in evaluation of gasdynamic heating and heat transfer process.
