Description/Abstract
The flow around an isolated wheel in contact with the ground is computed by the Un-steady
Reynolds-Averaged Navier-Stokes (URANS) method. Two cases are considered, a
stationary wheel on a stationary ground and a rotating wheel on a moving ground. The
computed wheel geometry is a detailed and accurate representation of the geometry used
in the experiments of Fackrell and Harvey. The time-averaged computed flow is examined
to reveal both new flow structures and new details of flow structures known from previous
experiments. The mechanisms of formation of the flow structures are explained. Surface
pressures and pressure lift and drag forces are computed and compared to experimental
results and show good agreement. The grid sensitivity of the computations is examined
and shown to be small. The results have application to the design of road vehicles.
