Abstract
The viscous flowfields of diffuser in altitude test cell were simulated based on the Reynolds-average unsteady Navier-Stodes equations with time-dependent method, MacCormack explicit scheme and Baldwin-Lomax algebraical turbulent model. The diffuser performance was calculated. The results show that the method of soluting Navier-Stokes equations is effective to predict the diffuser performance.
