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

Abstract

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