Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case.
Edmund Rumpler's 1921 Tropfenwagen was the first series-produced aerodynamically designed automobile, before the Chrysler Airflow and the Tatra 77. The drag coefficient is a common measure in automotive design as it pertains to aerodynamics. Drag is a force that acts parallel to and in the same direction as the airflow.
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.
In car design, ground effect is a series of effects which have been exploited in automotive aerodynamics to create downforce, particularly in racing cars.This has been the successor to the earlier dominant aerodynamic focus on streamlining.
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
Wunibald Kamm (26 April 1893 – 11 October 1966) was an automobile designer, engineer, and aerodynamicist.He is best known for his breakthrough in reducing car turbulence at high speeds; the style of car bodywork based on his research has come to be known as a Kammback or a Kamm-tail.
Spoilers are added to cars primarily for styling and either have little aerodynamic benefit or worsen the aerodynamics. The term "spoiler" is often mistakenly used interchangeably with "wing". An automotive wing is a device designed to generate downforce as air passes around it, not simply disrupt existing airflow patterns.
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.
