Isentropic Process Definition & Characteristics nuclear …

WebThis type of flow, with entropy constant along streamlines, is sometimes defined as isentropic. Flow with entropy constant everywhere is then called homentropic. See Compressible flow, Entropy, Isentropic process. Because of the second law of thermodynamics, an isentropic flow does not strictly exist. From the definition of … WebAs no heat is added or removed during the expansion, the process is described as being adiabatic and isentropic, that is, the entropy does not change. It must still be 6.141 3 kJ/kg °C at the very moment it passes the throat of the nozzle.

Web• For isentropic flow, look at effect of area change on M by comparing A at any point to area at sonic point (A*) – * refers to properties of a flow if isen. accel./decel. to M=1 sonic conditions (e.g., ρ*, T*,…) – alternative to stagnation as ref. state T T T T T T a a o o * * * = v v v * v* * * * a A a A o o ρ ρ ρ ρ = ρ ρ M 1 ... WebBut by using convergent nozzle we cannot obtain super-sonic flow. 2. When the flow is super-sonic, M > 1 . i.e. for super-sonic flow, the duct must be divergent. 3. The convergent-divergent nozzle is used for convert sub-sonic flow into super-sonic flow. In the convergent part the velocity of fluid is increased from sub-sonic to sonic condition.

WebWe know that, d A A = d P ρ v 2 ( 1 − M 2) The value of M = 1 gives dA = 0 which means that area is constant, i.e. at the point where the change in area is zero (at the throat), M becomes 1 and the flow-through nozzle reaches its maximum value and the nozzle gets chocked. When the flow becomes maximum, the pressure at the throat is called ... Websonic booms produced by supersonic projectiles and aircraft.
