Compressible Viscous Fluid Flow
The study of the flow of a compressible fluid is obviously more difficult than that of an incompressible fluid. The number of unknowns is increased, fluid properties are dependent on other variables, and the temperature field can no longer be decoupled from the flow field. Moreover, especially at high speeds, flow characteristics arc drastically changed by compressibility. But even for flows dominated by viscous effects, density variation may change the incompressible pattern, as may happen in flow within a cylindrical pipe when the transversal velocity is no longer zero (Kays, 1966).
