The structural instabilities of base flow in hypersonic wake flow over sphere are investigated by numerical simulation in this paper. Numerical simulation method is second-order accuracy NND scheme in spatial direction and Second-order Runge-Kutta scheme in temporal direction. Wakes flow of sphere at M∞=2, Re=1.71E+6(based on the sphere radius) and at M∞=6, Re=1.71E+6 are simulated. Stable solutions...
