Numerical Simulation of Rotor-stator Interactions in a Transonic Compressor Stage

摘要

A numerical method is developed for the simulation of rotor-stator interactions in a compessor or turbine stage. This method solves quasi-three-dimensional Navier-Stokes equations by an implicit high-resolution finite volume approach.A fully conservative method is designed to compute the inviscid and viscous fluxes 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 is discussed in terms of the computational results.
