DTNS3D Computer Code Simulation of Tip-Vortex Formation: RANS Code Validation

Abstract

This report describes results of an effort to simulate the formation of a tip vortex on a wing attached to a half-body and the propagation of the vortex downstream from the wing using the Reynolds averaged Navier-Stokes (RANS) computer code DTNS3D. Computational results are presented for the Baldwin-Lomax turbulence model. Three components of the mean velocity in four planes behind the wing are compared with measurements obtained in experiments performed in the MIT water tunnel. The axial component of vorticity is also compared with experimental measurements in the four planes.
