.... As the related drag penalty is minimal, aerodynamic efficiency is also improved with increasing rake angle. 31 08 2024 05 12 2024 10 02 2025 diffuser wind tunnel ground effect vortices automotive Diffusers, in an automotive context, are passive devices located at the rear...

...Y. E. William; S. Kanagalingam; M. H. Mohamed The underlying physics ever behind the aerodynamics of an airfoil in ground effect (GE) are still not fully resolved. In this work, the aerodynamics for an airfoil in GE is investigated computationally for both transitional and turbulent flow regimes...

... with the novelty of including the ground effect. The front wing of the formula one (F1) car can become flexible under the fluid loading due to elastic characteristics of composite materials, resulting in changing the flow field and eventually altering overall aerodynamics. The purpose of this study is to setup...

... the measurements and predictions agree quite well and they show a considerable increase in the yaw moment and side force at medium and high yaw angles. The axial drag force initially increases with yaw angle (up to 7.5 deg) and eventually decreases. Ground effects did not affect the overall loads, except...
