Fundamentals of Gas Dynamics
Gas dynamics is the field of study associated with the forces and motion of gasses. It is a subset of the general field of fluid dynamics that considers liquids in addition to gasses. Many fluids can be considered incompressible. This provides a degree of simplification to the equations that govern the motion of the fluid. A gas is compressible and the coupling between the fluid properties such as density, pressure, and temperature creates a close link between gas dynamics and thermodynamics. Choked flow and shock waves are two phenomena that are encountered with gases that are not generally encountered with liquids. These phenomena are directly related to compressibility effects.
