超临界压力航空煤油耦合传热计算方法研究
|
摘要
本文以超燃冲压发动机再生冷却技术为研究背景,对超临界压力航空煤油/壁面耦合传热计算方法进行讨论,分析了固体域与流体域耦合策略对于计算结果的影响。通过改变流-固界面的热边界条件,研究不同耦合策略的数值稳定性,并对计算效率进行了对比。结果表明:TFFB方法在求解毕渥数远小于1的问题时稳定性较差;hFFB方法在准确程度和计算效率上均表现最佳;使用Robin边界条件可以提高计算稳定性,合理选择虚拟对流换热系数可以提高计算效率。
Aiming at the regenerative cooling process of scramjet engines, the coupling method of conjugate heat transfer of structure/aviation kerosene at supercritical pressure is discussed. The influence of coupling procedures on the steady state solution is analyzed, both numerical stability and computational cost are compared by imposing different interface conditions. The results indicate that the TFFB procedure is unstable when the physical Biot number is much smaller than one. The hFFB procedure performs best in regard of both accuracy and efficiency. Numerical stability could be improved by imposing Robin condition on one side of the interface. Besides, choosing a reasonable value of the virtual heat transfer coefficient could improve the computational efficiency.
