Lowering the drag coefficient comes from streamlining the exterior body of the vehicle. Streamlining the body requires assumptions about the surrounding airspeed and characteristic use of the vehicle. Cars that try to reduce drag employ devices such as spoilers, wings, diffusers, and fins to reduce drag and increase speed in one direction. [4]
Downforce describes the downward pressure created by the aerodynamic characteristics of a car that allows it to travel faster through a corner by holding the car to the track or road surface. Some elements to increase vehicle downforce will also increase drag.
The rounded and tapered shape of the top of a car is designed to slice through the air and minimize wind resistance. [citation needed] Detailed pieces of bodywork on top of the car can be added to allow a smooth flow of air to reach the downforce-creating elements (e.g., wings or spoilers, and underbody tunnels).
Starting in the mid-1960s, 'wings' were routinely used in the design of race cars to increase downforce (which is not a type of ground effect). Designers shifted their efforts at understanding air flow around the perimeter, body skirts, and undersides of the vehicle to increase downforce with less drag than compared to using a wing.
A retractable front spoiler can reduce the scraping of the car on curbs or other road imperfections, while still reducing drag at high speeds. Powered fans, such as in the Chaparral 2J, do the equivalent of spoilers and increase the downforce, hence the traction and handling of the vehicle (See ground effect). Research continues on the use of ...
Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
Hulu has given a piot order to “Downforce” (working title), a comedy pilot written and executive produced by “Silicon Valley” writers Alec Berg and Adam Countee. The official logline for ...
Top: Lateral view; the red circles mark the front air dam/splitter and rear diffuser. Bottom: Rear. A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere.
