Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

We assume that flow conditions are steady (time independent), fully developed (fluid layers moving consistently), with laminar flow properties (no mixing or rotational fluid dynamic properties).
