Efficient Edge-Based Rotor/Stator Interaction Method

A method to address the rotor/stator interaction problem on an edge-based Reynolds-averaged Navier-Stokes solver is presented. The implementation of the phase-lagged boundary conditions and a new original conservative discretization of the sliding plane in an unstructured solver is discussed in detail. The numerical method is implicit in time, and convergence is accelerated using a multigrid technique where the coarser grids are obtained by agglomeration. Results of the present method are compared with the experimental results obtained at the National Aerospace Laboratory (The Netherlands) for a subsonic fan. [PUBLICATION ABSTRACT]
