Basic Compressible Flow topics include: Thermodynamics, compressibility and stagnation conditions.

Compressible flow is a branch of fluid mechanics that studies flows with significant changes in fluid density. In compressible flows, the fluid density and pressure depend on the velocity magnitude relative to the speed of sound in the fluid. 

Compressible flows are usually high-speed flows with Mach numbers greater than about 0.3. Examples of compressible flow include:
Flow over a wing or aircraft nacelle
Flow through high-performance valves 

Compressible fluid flow is different from incompressible fluid flow because the physical properties of the fluid depend on changes in container area, frictional forces along the walls, and heat transfer. 

The study of compressible flow is relevant to many fields, including:
High-speed aircraft
Jet engines
Rocket motors
High-speed entry into a planetary atmosphere
Gas pipelines
Commercial applications such as abrasive blasting
