The aerodynamic interaction of a rotating wheel and a downforce producing wing in ground effect
… characteristics of either an isolated downforce generating wing in ground effect or a rotating wheel in isolation. Investigations that have considering both bodies working in unison conflictingly claim that the addition of a wheel downstream of a wing can aid or hinder the performance …

Wake deceleration of a racecar multielement airfoil in ground effect
The importance of aerodynamic downforce in competitive motorsports has been well established. Much of this aerodynamic downforce is produced from the inverted multielement wings at the front and the rear of the car. While such a high-lift system is capable of producing high downforce as a result of …

Investigation of the Under-Body Flow Field of a Prototype Long-Range Electric Vehicle
… change in pressure drag, but the shear drag and downforce increased. The ride height was increased to reduce drag and downforce; this change did not have a significant effect on the resultant forces and the separation on the underbody was largely unchanged. The diffuser was extended by 12.7 cm …

Aerodynamic interaction of an inverted wing with a rotating wheel
… vortex interaction in the wheel wake. The wing downforce increases at low ride heights due to the wheel presence, but reduces at high ride heights. The modified channeling effect, vortex and separation effects govern the wing flow field, although the wheel circulation acts as an additional …

Design of Chassis, Impact Attenuator, Suspension and Aerodynamic Systems of a Formula SAE Car
… An undertray diffuser design was compared to the downforce generation capabilities of a side wing, both within the available space limits, and the side wing was found to be generating more downforce. Loads acting on suspension links were found out by calculating the load transfer expected to …

Aerodynamics and multi-fidelity surrogate modelling of an inverted wing with vortex generators in ground effect
… flow separation, with a resultant improvement in downforce within relatively low drag penalty. The results also reveal fundamental vortex characteristics for flow separation control.<br/><br/>A computational study is performed by three-dimensional Reynolds-averaged Navier-Stokes steady simulations …

Quantitative multifactor analysis of planter settings and row unit design for corn stand establishment in precision agriculture
… factors, including planting speed, hydraulic downforce application, and row unit arrangement, significantly influence the quality of seed-to-soil contact and the integrity of furrow closure, which in turn affects early seedling emergence and final stand uniformity. Nonetheless, there exists a …

Development and application of an integrated aerodynamic and thermodynamic testing system for cars
… can significantly alter the drag force and downforce on cars. However, a little angularity of a device, such as the side front canards, to the flow direction, can significantly alter its function. The flow visualization test showed that the local flow direction strongly depends on the local …

Tire Deformation Modeling and Effect on Aerodynamic Performance of a P2 Race Car
… goals such as drag reduction, maximizing downforce and side force, and maintaining balance. Commonly, these goals are to be met at the same time thus increasing the level of difficulty to achieve them. The methods for data acquisitions available to a race team during the season is mostly …

Computational Fluid Dynamics Analysis of Inverted, Multi-Element Airfoils in Ground Effect
… lift for the race car. This negative lift, or downforce, increases the amount of traction between the race car’s tires and the ground ultimately allowing the drivers to turn at faster speeds. Commonly used aerodynamic devices are a front and rear wing; the wing cross sections are defined by …

Design and analysis of active aerodynamic control systems for increasing the safety of high-speed road vehicles
… On the other hand, at high speeds, significant downforce can be generated by employing aerodynamic wings on the vehicle body to enhance its road holding ability. A split rear wing is proposed to control the aerodynamics of high-speed road vehicles to closely manipulate the dynamics of the …

Direct numerical simulation of an aerofoil at high angle of attack and its control
… the trailing edge generated vortices, limits the downforce generated by those vortices also regularising the shedding cycle that appears to be much more organised when the flaplet is activated. A similar study has also been carried out for the dynamic case. We have analysed the effects produced by …
