摘要
Some implicit time-marching finite-difference solutions of time-averaged Navier-Stokes equations for two- dimensional compressible internal flows are presented.Five numerical examples including subsonic,transonic, supersonic and hypersonic flow fields with steady and unsteady phenomena show validity and flexibility of the present calculation code.The TVD scheme suggested by Harten et al is used to improve the shock resolution, and an algebraic turbulence model suggested by Baldwin and Lomax is introduced to evaluate the viscous effect in the turbulent flows.It is found that the computational results show fairly good agreement with the experi- mental data.
