Experimental study of Aerodynamics over a flat plate.
... In our world the aerodynamics phenomena can be found anywhere. For example: we use airplanes and cars which all affected by the air flow. The air flow can generate lift under airplane wings which make it possible to fly, the same air flow can generate drag force over a solid body, such as a hand tha ...

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) refers to forces acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity.Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity.Drag forces always decrease fluid velocity relative to the solid object in the fluid's path.
