• Isentropic process — In thermodynamics, an isentropic process ( iso = equal (Greek); entropy = disorder ) is one during which the entropy of the system remains constant. [Van Wylen, G.J. and Sonntag, R.E., Fundamentals of Classical Thermodynamics , Section 7.4]… …   Wikipedia

• Gas Dynamics Shocks — Shock in Gas Dynamics Terminology means an abrupt discontinuity in the flow field. It occurs in flows when the local flow speed exceeds the local sound speed. To put it in other words it means when the Mach number of the flow exceeds 1 , then… …   Wikipedia

• Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… …   Wikipedia

• Fanno flow — refers to adiabatic flow through a constant area duct where the effect of friction is considered. Compressibility effects often come into consideration, although the Fanno flow model certainly also applies to incompressible flow. For this model,… …   Wikipedia

• Rayleigh flow — refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible… …   Wikipedia

• Homentropic flow — In fluid mechanics, a homentropic flow has uniform and constant entropy. It distinguishes itself from an isentropic or particle isentropic flow, where the entropy level of each fluid particle does not change with time, but may vary from particle… …   Wikipedia
