What is Rayleigh line & fanno line?
Considering this, what do you understand by choking in Rayleigh flow?
Rayleigh flow refers to frictionless, non-Adiabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Heat addition will cause both supersonic and subsonic Mach numbers to approach Mach 1, resulting in choked flow.
Furthermore, what is meant by isentropic flow? In fluid dynamics, an isentropic flow is a fluid flow that 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.
Just so, what is choking in Fanno flow?
Fanno flow is the adiabatic flow through a constant area duct where the effect of friction is considered. For a flow with an upstream Mach number greater than 1.0 in a sufficiently long enough duct, deceleration occurs and the flow can become choked.
What is sonic flow?
Answered Mar 17, 2018. Subsonic flow is a flow which has a velocity lower than the velocity of sound. In other words, the fluids which has a Mach number less than 1. Sonic flow is the flow which has the same velocity as the sound. In other words, the fluids which has a Mach number equal to 1.
