WebCompressible flow differs from incompressible flow in at least the following respects: 1. The density of the flow becomes a variable. 2. The flow speeds are high enough that the flow kinetic energy becomes important and therefore energy changes in the flow must be considered. This couples the science of thermodynamics into the aerodynamic ... WebFeb 10, 2016 · $\begingroup$ @Paul this is derived from the conservation of momentum. it is not so much a "rule" as a suggestion. if you don't care about 10% (or higher) changes in density (or other quantities), go ahead and use the incompressible relations for high Mach numbers. if you do care about small changes in density, then use the compressible ...
