Aerodynamic characteristics of a wing-and-flap configuration in ground effect and yaw

Abstract: The influence of yaw on a model representative of a monoposto racing car front wing and nose section operating in close proximity to the ground is discussed. The yawed condition is representative of a car operating in a crosswind or with side-slip whilst cornering. Due to the need for downforce in corners rather than on a straight it is standard practice to test a racing car at varying orientations of yaw, pitch and roll quasi-statically. Wind tunnel testing with a 50% scale model at a chord-based Reynolds num… Show more

“…An asymmetric pressure distribution was present with one side of the wing producing more downforce than the other [16]. In the wake, all vortices formed by the lateral movement in the same direction as the mean flow were strengthened whilst those formed against the mean flow were weakened [16]. Under the cornering condition, downforce was reduced whilst drag increased [7].…”

“…Under the yaw condition, both drag and downforce reduced. This was attributed to a reduction in effective diffuser angle, loss of vortex enhancement and a change of stagnation locations [16]. An asymmetric pressure distribution was present with one side of the wing producing more downforce than the other [16].…”

“…The aerodynamic analysis of wings operating in ground effect has previously been conducted through both experimental and computational means . The computational studies [13][14][15][16][17][18][19][20][21][22][23] have, in general, used…”
