【摘要】：为了验证牛顿流理论的效度,在高超声速高温气体效应下设计验证模型,对比牛顿流理论解析解和数值模拟结果,证明牛顿流理论在高温气体效应下仍然具有相当高的效度。研究表明完全气体模式下的牛顿理论仍然可以移植到高温气体情形下,在高温气体效应下为飞行器设计提供前期的概念指导。
[Abstract]:In order to verify the validity of Newtonian flow theory, a validation model was designed under hypersonic and high-temperature gas effects. Compared with the analytical solution of Newtonian flow theory and numerical simulation results, it is proved that Newtonian flow theory still has high validity under high temperature gas effect. It is shown that Newtonian theory in complete gas mode can still be transplanted to the case of high temperature gas, and it can provide conceptual guidance for aircraft design in the case of high temperature gas effect.
