气动加热与结构热烧蚀松耦合模型及其实现

高超声速气动热现象复杂,是高超声速飞行器热防护设计的关键技术之一。提出了一种双向耦合的多场耦合模型,实现了高声速化学非平衡气动热与结构烧蚀一体化模拟方法。针对典型飞行器结构进行了高超声速条件下的数值模拟与分析,验证了一体化模拟方法与计算程序的有效性,表明其可为相关工程提供有力的分析工具。

Numerical precidition on the complex hypersonic aerothermodynamics phenomena is one of key technologies.In this paper,a numerical simulation framework for hypersonic non-equilibrium aerothermodynamics,structure condition and alabiton phenomena is successfully developed,based on several verified software.Typical hypersonic vehicle configurations are numerically simulated and anaylzed using the proposed framework.The results show that it can be a powerful tool for such complicated engineering problems.
