Previously derived equations describing compressible flow have been rearranged in terms of known downstream conditions to facilitate determination of unknown upstream conditions. A 650 I.B.M. computor was used to solve the simultaneous equations numerically to permit construction of convenient design ...
The flow of compressible fluids (e.g., gases and vapors) through pipelines and other restrictions is often affected by changing conditions of pressure, temperature, and physical properties. The densities of gases and vapors vary with temperature and pressure (PV = constant). Conversely, in adiabat...
“Compressible fluid” is known as those fluids if its density varies with pressure caused by the flow. If density does not change or changes slightly then it is known as an "incompressible fluid".Share “Compressible or incompressible fluid” is a subject of gas dynamics or chemical ...

including multiple fluids, all gases in the simulation will be treated as compressible using variable density with the ideal gas law. All liquids (here it seems you are using water) in a simulation with multiple fluids are treated as incompressible, regardless of whethercompressibilityis turned on...

Fluid mechanics - Hydrodynamics, Flow, Pressure: Up to now the focus has been fluids at rest. This section deals with fluids that are in motion in a steady fashion such that the fluid velocity at each given point in space is not changing with time. Any f
