To combat the effects of front end lift, APR Front Wind Splitters are utilized to give extra traction and control in the front of a car. By creating a high pressure area on top of the wind splitter, high pressure air flow is restricted to flow underneath a car. With low pressure below the car, the effect of lift is reduced and a driver can gain from the extra traction and control.
Carbon Fiber Reinforcement
All APR Front Wind Splitters are reinforced with sheets of carbon fiber.
Fully Functional Undertray
Our Front Wind Splitters are not just add on cosmetic pieces. Every APR Front Wind Splitter completely covers the entire area below a cars front bumper. This allows for smoother air flow below the front bumper, creating more efficient downforce.
Support Rods Included
Supporting every APR Front Wind Splitters are stainless steel Support Rods.
Computational Fluid Dynamics (CFD)
What is Computational Fluid Dynamics (CFD):
Computational fluid dynamics is a specialized sub-discipline of fluid mechanics (the study of fluid physics) that involves using algebraic equations to solve fluid flow problems. CFD has origins in the aerospace industry dating back to the 1960s, where companies such as NASA, Boeing, Lockheed, and others developed their own CFD programs to perform the analysis needed for their aircraft designs.
Using mathematical modeling and numerical methods, computations performed using powerful CFD software enable us to quickly predict and simulate what will occur in fluid flow situations (velocity, pressure, density, and temperature vs. time). In comparison to performing experiments in wind tunnel laboratories, CFD allows us to perform simulations in much more cost-effective, virtual laboratories.
CFD in motorsports:
CFD is used successfully in all the top levels of motorsports, including Formula One, IndyCar, and even NASCAR. CFD is even used by car manufacturers in the development of many of today's road cars. Companies have invested tens of millions of dollars, if not more, to implement CFD design in their product. As a disclaimer, CFD is not 100% accurate. Many factors can affect the accuracy of CFD simulations, including accuracy of mathematical models, limits in computing power, and the scientist's ability to interpret the data that that comes out of the computer.
Despite its lack of total accuracy, modern-day aerodynamic design could not have progressed to its current state without the help of CFD. The results of CFD-developed automotive products are real, and can easily be seen in both race cars and road cars.
