Abstract
A computer-based method of simulating rotor-stator unsteady turbulent flow interaction in turbomachinery, which includes performing CFD ensemble-averaged flow field simulation over the coarse mesh and performing CFD large eddy simulations over the fine meshes, the ensemble-averaged and large eddy simulations being coupled to each other, and the large eddy simulations of the regions of the selected blade passages being used to derive unsteady turbulence stress terms in the ensemble-averaged simulation for corresponding regions of the blade passages of the first and second rows without fine meshes.
