Thermodynamics Directory Heat Transfer Directory Anisentropic processis one in which the entropy of the fluid remains constant. This will be true if the process the system goes through is reversible and adiabatic. An isentropic process can also be called a constant entropy process. ...
Fluid Flow Engineering and Design Thermodynamics Isentropic Flow Relationships A isentropic flow is when a fluid flow is both adiabatic and reversible. That is, no heat is added to the flow, and no energy transformations occur due to friction or dissipative effects. For an isentropic flow of a ...
Thesecond law of thermodynamicsrequires that the adiabatic and frictionless flow of any fluid results in no change in entropy. Constant entropy flow is calledisentropic flow. Based on the equation ofentropy in a compressible flow: ds = cvln(T2/ T1) + R ln(ρ1/ ρ2) ...

The corollary of second principle of thermodynamics (known as principle of increase of entropy S) says: (dS)_adiabatic >= 0 The equality sign holds when no dissipation is involved (i.e. reversible process). If dissipation plays a role, then the inequality applies. ...
In general, from nonequilbrium thermodynamicsdS = diS + dQopen/T + dmatterSThe last term accounts the transfer of matter with exterior and diS is the production of entropy due to irreversible phenomena. The form of production term is standard and known by decades: the product of thermodynamic...
