ABSTRACT
When objects move through air, forces are generated by the relative
motion between the air and surfaces of the object. Aerodynamics is the study of these
forces, generated by the motion of air, usually aerodynamics are categorized according to
the type of flow as subsonic, hypersonic, supersonic etc.
It is essential that aerodynamics be taken in to account during the
design of cars as an improved aerodynamics in car would attain higher speeds and more
fuel efficiency. For attaining this aerodynamic design the cars are designed lower to the
ground and are usually sleek in design and almost all corners are rounded off, to ensure
smooth passage of air through the body , in addition to it a number of enhancements like
spoilers, wings are also attached to the cars for improving aerodynamics. Wind tunnels are
used for analyzing the aerodynamics of cars , besides this a number of software‟s are also
available now days to ensure the optimal aerodynamic design.
