摘要：
In this paper, Gortler instability for hypersonic how over a concave surface is investigated using two approaches: Linear Stability Theory(LST) and Direct Numerical Simulation(DNS). Initial forcing disturbances are obtained from the LST, and subsequent linear and nonlinear development is simulated using Navier-Stokes equations. We investigate linear and nonlinear growth of Gortler vortices in hypersonic boundary layers.
