Compressible flow

Compressible flow or gas dynamics is a branch of fluid mechanics that deals with flows having significant changes in fluid density.

• the study of motion of gases and its effects on physical systems
• based on the principles of fluid mechanics and thermodynamics
• gases flowing around or within physical objects at speeds comparable to the speed of sound
