摘要
采用非定常数值模拟方法对某型号远程导弹头部气动加热问题进行了研究。提出了一种流固耦合的计算方法,在求解流体力学控制方程组的同时,求解流体与固体表面的热传递方程以及固体区域的能量方程。计算获得了各个时刻流场内的温度、压力、速度等参数的空间分布,同时得到了导弹头部固体区域及导弹内部的温度变化。研究表明,采用流固耦合方法对气动加热问题进行模拟,可以得到合理可用的弹表温度数据。
Unsteady simulation of aerodynamic heating process of certain long-distance missile＇s head is presented. A method of fluid-solid coupled is put forward. Equation of heat exchange between fluid and solid and energy equation of solid zone are solved while basic fluid equations are solved. Aerodynamic data of different height and temperature change at solid zone and inner of the missile are obtained through simulation. As a result, the data of temperature is reasonable through the simulation using the method of fluid-solid coupled,
