摘要
利用高精度的有限体积迎风格式TVD来求解超声速流场,利用有限元方法求解固壁的温度场,流场与结构温度场互为边界条件交换数据,实现流场解算与温度场解算的耦合数值分析,耦合方法研究表明气动加热问题属于强耦合,耦合迭代直接影响温度平衡时间.因此采用小时间步的耦合计算可以准确预测高速飞行器的气动加热.
The upwind TVD and finite volume method are employed to solve the supersonic flow field, and the finite element method or finite difference method is employed to solve the solid wall temperature distribution. The two parts work together, each one provides a boundary condition for the other, and exchanges information through the solid wall surface. This technology provides an efficient way for aerothermal problems.
