Application of high accuracy Penalized Vortex in Cell method for the high Reynolds number turbomachinery flows.

Abstract This paper presents the high-order Penalized Vortex in Cell method applied to flow past an airfoil with a cavity and T-106A turbine cascade. The first part of treats about parallel environment algorithm performance where times for each operation are measured. Then further validation on cylinder at Re=9500 was shown, simulation results were extended. For unbounded stream-function correction based Biot-Savart law, velocity profiles boundary shown. A volumetric imbalance determined. In second part, formulation pVIC periodic flows discussed, example calculation cascade moving bar wake generator demonstrated.
