Compressible Fluid Flow topics include: Normal shocks, pressure pulse in fluids, isentropic flow and choking. Compressible fluid flow is a branch of fluid mechanics that deals with flows where the fluid density changes significantly. 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 Flow of air over an aircraft wing Combustion gases in a jet engine  Compressible fluid flow is different from incompressible fluid flow because the...
