本文发展了一种在一般乘积黎曼流形上分解亚音速椭圆-双曲复合混合型三维定常可压Euler方程组的方法。应用该方法研究了多维边界条件扰动下R3空间球对称亚音速流和跨音速激波的稳定性。
We develop a method that works in general product Riemannian manifold to decompose the three-dimensional steady full compressible Euler system, which is of elliptic–hyperbolic composite-mixed type for subsonic flows. The method is applied to show stability of spherically symmetric subsonic flows and transonic shocks in space R 3 under multidimensional perturbations of boundary conditions.
