Numerical computation of rotor-stator interactions in a transonic compressor stage by solving navier-stokes equations

摘要

A numerical method is developed for the simulation of rotor-stator interactions in a compressor or turbine stage. This method solves quasi-dimensional Navier-Stokes equations by an implicit high resolution finite volume method. A fully conservative method is designed to compute the inviscid and viscous flux at the interface of rotor and stator grids. Numerical results of rotor-stator interactions in a transonic compressor stage are presented. The mechanism of rotor-stator interactions in this compressor stage in discussed in terms of the computational results.
