Laser Doppler anemometry measurements in the near-wake of an isolated Formula One wheel. Experiments in Fluids, Volume 42, Issue 5, May 2007, Article number 6710723-4864http://dx.doi.org/10.1007/s00348-007-0273-7http://dspace.lib.cranfield.ac.uk/handle/1826/7507An experimental investigation was conducted to identify the main structures in the near wake of an isolated Formula One wheel rotating in ground contact. A 50 percent-scale isolated wheel assembly, geometrically similar to the configuration mounted on a Formula One racing car, was tested in a closed-return three-quarter open-jet wind tunnel. The test Reynolds number, based on wheel diameter was 6.8 × 105. Using laser doppler anemometry, three velocity components were measured with a total of 1966 data points across four planes and within one diameter downstream of the wheel axis. Based on analysis of these data, the main characteristics of the near-wake of an isolated wheel rotating in ground contact are presented. A revised model of the trailing vortex system induced in the wake of such a wheel is proposed, which clarifies the contradictory ones published in the literature to dateArticle
