热化学非平衡流辐射流场工程计算方法研究

NUMERICAL STUDY OF THERMOCHEMICAL NONEQUILIBRIUM RADIATION FLOWFIELD ENGINEERING CALCULATION

从耦合辐射的轴对称热化学非平衡 N-S方程出发 ,采用双温度、1 1组元反应气体模型 ,耦合修正的Nicolet单温度辐射模型 ,利用隐式 NND有限差分格式和时间预处理技术数值求解了 FIREII飞船热化学非平衡辐射流场 。

The symmetric thermochemical nonequilibrium radiation flow is simulated numerically. The full Navier Stokes equations are taken as the governing equations. The two temperature and eleven species gas model is considered. The improved Nicolet 'one temperature' radiation model is used. NND scheme for shock capture and time preconditional matrix technique are used for numerical solution. The result of radiation heat is got for contrasting with experiment result.
