“…Moreover, and to our knowledge, the proposed study is the first aerodynamic simulation and experiment on the whole wheel sub-system including the effect of the wheel fender. The literature review shows, however, some detailed studies of an open rotating wheel of a formula 1 racing car [10][11][12][13][14].…”

“…Purvis concluded mainly that as contact patch size (tire deformation) increases, the lobe vortices significantly increases. The second was by WÄaschle [10] who was the first to perfectly simulate a rotating wheel in contact with a moving ground using the direct method. His measurements were qualitatively in the same direction as the previously mentioned facts about the net lift and drag forces.…”

“…This was only proposed theoretically by Fackrell [5] in a non-approved manner. The next was Van Den Berg [9][10][11][12][13] whose work focused on investigating the aerodynamic interaction between the rotating wheel and the front inverted wing. Although his measuring arrangement was similar to that used by Fackrell, he didn't rely on the data collected by Mears which successfully captured the suction peak.…”

A model of Formula One racing car rotating dry wheel in contact with the ground is studied using a computational approach as a validation case. This validation case focuses on the computed surface pressure around the wheel's center line. This computed result is compared to an experimental one obtained from the available literature work and it showed good agreement. Another case study is considered with replacing the dry wheel model with another wetcondition wheel model. The wet-condition wheel's work is mainly concentrated on the developed aerodynamic forces especially the wheel moment values. This moment is translated to an expression of resistive torque developed by the air stream on the wheel and computed in each case study. In addition, general schematic pictures of the flow behavior around the wet wheel are presented.

“…Skea and Bullen [9] carried out CFD simulations and experimental validations to analyse the effect of wheel rotation, wheel width and wheel arch characteristics on wheel flow field. Wray [19], Wäschle et al [22], Mears and Dominy [20], McManus and Zhang [21], and Saddington et al [8] performed computational and experimental investigations on stationary as well as rotating isolated automotive wheels. Effect of yaw angle [19] and numerical codes used [20] was studied with varying degrees of success.…”

“…The above discussion shows the severe limitations of existing experimental techniques in investigation of flow inside a wheel arch. Computational techniques have also been employed to quantify the pressure and velocity distribution around automotive wheels [1,7,9,[18][19][20][21][22]. Skea and Bullen [9] carried out CFD simulations and experimental validations to analyse the effect of wheel rotation, wheel width and wheel arch characteristics on wheel flow field.…”

Detailed flow measurements are essential for analysing flow structures found in confined spaces, particularly in various automotive applications. These measurements will be extremely helpful in solving flow dependent complexities. Although considerable progress has been made in computational techniques for investigating such flows, experimental flow measurements are still very difficult to carry out therein. Flows mapped using an array of robust instruments like multi-hole pressure probes can provide significant insight into the flow field of such complex flows. Pressure probes can withstand the harsh environments found in such applications; however being intrusive devices significant interference in flow field can limit their applicability. This paper presents an investigation of three-dimensional interference caused by multi-hole pressure probes in an automotive wheel arch. It involves simulation of flow around a pressure probe inserted at various locations within the wheel/wheel arch gap. Pressure and velocity fields along longitudinal and lateral planes have been mapped and the extent of interference caused by the probe along three orthogonal axes has been presented. A three-dimensional ellipsoid of interference has been defined to assist in recommending optimal placement of probes and minimise the error due to interprobe interaction, thus enhancing the measurement accuracy of transient flow phenomena.
