对于高超声速流场和固体结构温度场的耦合传热问题,推导出了一种新的界面耦合处理方法,通过在流固交界面上求解由狄里科利和牛顿边界条件得出的偏微分方程,把对流体和固体两个区域的影响显式地体现在交界面方程中,并对该方法进行了稳定性分析.分析表明:该方法相比于传统的耦合迭代方法有更好的稳定性.将这套算法成功应用于绕无限长圆柱的气动加热计算中,对圆柱在气动加热过程中的温度变化做了比较详细的分析.
For coupled heat transfer between hypersonic flow field and solid structure temperature field, a new interface coupling method is derived. By solving the partial differential equation (DEP) derived from the boundary conditions of Dilikoli and Newton at the fluid-solid interface, , The influence of both the fluid and the solid in the two interfaces of the interface is explicitly expressed in the interface equation and the stability of the method is analyzed.The analysis shows that this method has better stability than the traditional coupling iterative method The algorithm is successfully applied to the calculation of the aerodynamic heating around an infinite cylinder, and the temperature change of the cylinder during the aerodynamic heating is analyzed in detail.
