Abstract

Computational Fluid Dynamics simulations have been performed using RANS and URANS in order to observe the fundamental flow features and differences between various ramp vortex generator geometries. Both forwards and backwards generator geometries have been tested in 3 configurations. From the analysis it was found that the backwards facing ramp produced superior flow entrainment to the near wall region to the forwards facing ramp in a relatively thick boundary layer. A new method for the rapid visualisation of vortex cores has also been proposed.
