  Aerodynamics - Wikipedia, the free encyclopedia
Aerodynamics is a branch of fluid dynamics concerned with the study of forces and gas flows.
The aerodynamics of internal passages is important in heating/ventilation, gas piping, and in automotive engines where detailed flow patterns strongly affect the performance of the engine.
Aerodynamic problems are solved using the conservation laws, or equations derived from the conservation laws.

 R&T - Technology Update: Automotive Aerodynamics (6/2002)
Aerodynamic development of a new BMW is an iterative process, with priorities given to rear regions, underbodies, wheel housings and cooling airflow, in that order.
Like the airflow sensors in automotive fuel injection systems, this one uses hot wires, three that are mutually perpendicular to get an extremely accurate x-y-z plot of the localized flow.
The car's rotating wheels are mounted independently; this, to isolate their belt-driven forces from primary aerodynamic measurements.

 Automotive E-coat Paint Process Simulation Using FEA
It is well known that the layout of the anodes and the automotive body have a significant impact on the overall electrical resistance of the system, and thus the amount of current that must be delivered.
E-coat paint as it is used in automotive plants is very different from electrostatic paint applications where extremely high voltages and very small electrical currents are used to apply top coats to conductive wares.
The automotive body is designed by an individual or team that is principally responsible for strength and rigidity as well as minimization of vibration or harmonics.

The angular outside contours of the living model were adapted in the area of the roof and side skirts, as was the prominent, descending rear end with its heavily scalloped sides and pronounced wedge shape.
In doing this they were disobeying important principles in automotive aerodynamics, and were all the more surprised at the results: the Cd value for the car was 0.095.
In aerodynamic terms it was just as good as the shape as measured on the ground considered ideal by aerodynamics specialists (Cd 0.09).

Aerodynamics is the branch of dynamics that treats of the motion of air (and other gaseous fluids) and of the forces acting on solids in motion relative to such fluids.
Aerodynamics falls into velocity ranges, depending upon whether the velocity is below or above the local speed of sound in the fluid.
The hypersonic regime is that speed range usually in excess of five times the speed of sound.

 Ground Effect   (Site not responding. Last check: 2007-09-21)
The effect that wings can have on automotive aerodynamics was not noticed until much later when racing car designers stated to use inverted wings to create downforce and enable higher cornering speeds.
Although some of these interesting topics arise because of either new aerodynamic concepts or new measurement systems, there is still misinterpretation in fundamental mechanisms of ground effect aerodynamics due to incorrect models, boundary conditions, or simulations.
Before the development of the experimental facilities in the ground effect aerodynamics laboratory, a detailed investigation was conducted of the specific conditions needed for accurate and reliable ground effect simulations.

Auto Aerodynamics 101 by Dan Jones It's been over a decade since I had my aerodynamics courses (basic aerodynamics, gas dynamics, fluid flow, and boundary layer theory), so I probably remember just enough to be dangerous.
While this is an aerodynamically efficient shape for a supersonic transport, it is not an efficient shape for a subsonic one.
The point is that aerodynamics is a complex field of study and it takes a well educated eye not be misled.

One goal for the teams who design solar cars, is to achieve extremely low aerodynamic drag while still maintaining a suitable surface for the solar cells and adequate space for the driver and the other components.
One objective of aerodynamic studies is the design of shapes that offer the least resistance to the flow of air.
Aerodynamics engineers study the way in which air flows around objects, but it is still somewhat a fl art.
