Prediction and physical analysis of unsteady flows around a pitching airfoil with the dynamic mesh approah

Abstract

The fluid structure interaction due to the pitching motion of a NACA0012 aerofoil has been studied numerically at moderate and high Reynolds numbers. The dynamic mesh method has been employed in the code ICARE/IMFT solving the Navier-Stokes equations in compressible flows. At high Reynolds number, the phase-averaged Navier-Stokes equations have been solved, coupled with advanced URANS modelling in the NSMB code. The vortex dynamics and especially the stall are physically captured by the dynamic mesh method and by the URANS/Organised Eddy Simulation approach.
