Advanced Experimental and Numerical Validation and Analysis of Propeller Slipstream Flows

摘要

Acomparison of velocity(-derived) quantities ismade in the slipstreamof a turboprop-equipped transport aircraftnbetween phase-locked experimental Particle Image Velocimetry data and unsteady Reynolds averaged Navier–nStokes calculations. Velocity results indicate a high level of agreement between the numerical and experimentalnresults. In addition to velocity vector data, other derived quantities, such as vorticity, allow a verification andnvalidation of the modeling in Computational Fluid Dynamics. Although a good agreement is achieved, future needsnfor the comparison and validation of computational (Computational Fluid Dynamics) and experimental (ParticlenImage Velocimetry) data are highlighted.
