Windsor Body 2.5 degree yaw unsteady CFD Simulation

This is a simulation of the Windsor body at 2.5 degree yaw in the Loughborough University wind tunnel. It is a test case in the Third Automotive CFD Prediction workshop. An isosurface of the Q criterion parameter is used to extract vortex cores and the video shows the unsteadiness in the wake. The four green planes correspond to the location of the laser sheets used in the experiment to measure the velocity field. The second video animates the velocity field in the laser sheets in a similar manner to the experimental PIV measurements. The calculations were carried out using STAR-CCM+ 17.02 on the standard workshop grid g2 and with a Detached Eddy Simulation to capture the large scale turbulence.
