摘要
本文以旋转叶轮内三元流动正命题变分原理为理论基础,应用有限元与人工密度相结合的方法,进行跨声速流动激波的捕捉工作,结果表明,这种方法是可行的。
According to the theory of variational principle for aerodynamic direct problem on 3-d transonic flow with shock waves in a rotating turbo-impeller, a combined version of finite element method and artificial compressibility method is proposed for capturing the shock waves on the transonic flow. The results show that this version is reliable and practicable.
