APPLICATION OF TENSOR EQUATIONS IN COMPUTATION OF THREE DIMENSIONAL VISCOUS FLOW
-
摘要: 本文采用张量形式的粘性激波层方程,用空间推进的数值方法计算了球锥、椭球锥有攻角高超音速绕流问题,并计算了组合椭球锥的粘性绕流,从而说明了本文的方法可推广应用于一般外型飞行器的小攻角绕流计算问题。文中考虑了在高超音速流动条件下空气的非平衡化学反应,认为化学反应的速率是有限的Abstract: The tensor viscous shock-layer equations are used for computing thehypersonic viscous flow over sphere-cone and ellipsoid-cone with angle of attack. The results show that the method can be applied to compute the flow over a complex geometry. The none-quilibriurn chemical reactions of hypersonic flow are considered, the chemical reactions are assumed to proceed at finite rate.
