About: Non ideal compressible fluid dynamics

Non ideal compressible fluid dynamics is a branch of fluid mechanics studying the actual characteristics of dense vapors, supercritical flows and compressible two-phase flows, namely whereby the thermodynamic behavior of the fluid differs considerably from that of a perfect gas. At high reduced pressure and temperature, close to the saturation curve the speed of sound is largely sensitive to density variations along isentropes. Consequently, the fluid flow departs from the ideality assumption and under particular conditions may even exhibit non classical gas dynamic phenomena, whose nature is governed by the value of the fundamental derivative of gas-dynamics Γ. A non-monotonic Mach number trend along an expansion is typical for 0 < Γ < 1, while for Γ < 0 values admit the occurrence of inv
