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 physical properties of the fluid depend on changes in container area, frictional forces along the walls, and heat transfer. Compressibility is defined as the fractional change in the volume of a fluid in response to a small change in pressure. Compressible Computational Fluid Dynamics (CFD) can be used for simulation of compressor stage performance and as data generation tool in a blade shape.
