Abstract

The effect of a front wheel behind a front wing (on an open wheel racing car) was studied using Computational Fluid Dynamics (CFD). Results are presented for a 2D analysis conducted on an aerofoil and cylinder. CFD models are used to compare and demonstrate the effect that these two objects have on each other, when operating in close proximity. From the CFD analysis it was determined that the aerofoil generates lift, instead of the desired downforce in several of the configurations studied and only in certain positions is the aerofoil beneficial. This may explain the reduction in the front wing span that teams adopted after the Formula One (F1) regulation changes for the 1998 season.
