Definition of a front splitter - Front splitters are essential aerodynamic components that serve to balance the front vs. rear distribution of downforce. A splitter is typically found on the front-end of a race car, appearing as a flat extension to the very bottom of the front bumper.

What is a front splitter

  A front splitter is commonly used to increase the amount of down force at the front of the car. The airstream is brought to stagnation above the splitter by an air dam, causing an area of high pressure. Below the splitter, the air is redirected away from the stagnation zone and is accelerated, causing the pressure to drop. This, combined with the high pressure over the splitter, creates down force. The larger the extension area of the splitter is the more down force is generated. In most closed-wheel race cars, the underside of the splitter smoothly integrates with the under tray, creating one large flat plane that is driven by the rear diffuser.


 Using fluid dynamics by way of Bernoulli's equation (pressure) + 0.5(density)X(velocity)2 = constant says the increase in pressure must be accompanied by a decrease in velocity, and vice versa. Integrating the static pressure along the entire surface of an airfoil gives the total aerodynamic force on a body.


 Famously the Coanda effect which was named after Henri Coanda who built and flew the first jet powered aeroplane demonstrates that a moving stream of fluid in contact with a curved surface will tend to follow the curvature of the surface rather than continue traveling in a straight line.
