Abstract

A comparison of velocity(-derived) quantities is made in the slipstream of a turboprop equipped transport aircraft between phase-locked experimental Particle Image Velocimetry (PIV) data and unsteady Reynolds Averaged Navier-Stokes (uRANS) calculations. Velocity results indicate a high level of agreement between the numerical and experimental results. In addition to velocity vector data, also derived quantities, such as vorticity, allow a verification and validation of the modeling in CFD. Although a good agreement is achieved, future needs for the comparison and validation of computational (CFD) and experimental (PIV) data are highlighted.
