Toward improved simulation tools for compressible turbomachinery: assessment of Residual-Based Compact schemes for the transonic compressor NASA Rotor 37
Article dans une revue avec comité de lecture
Residual-based-compact schemes (RBC) of 2nd and 3rd-order accuracy are applied to a challenging 3D ow through a transonic compressor. The proposed schemes provide almost mesh-converged solutions in good agreement with experimental data on relatively coarse grids, which allows achieving a given accuracy level with computational cost reductions by a factor between 2 and 4 with respect to standard solvers.
