An isentropic process is a thermodynamic process in which the entropy of the fluid or gas remains constant. It means the isentropic process is a special case of an adiabatic process in which there is no transfer of heat or matter. It is a reversible adiabatic process.The assumption of no heat transfer is very important since we can use the …
WebJun 27, 2024 · In conventional thermodynamic language "adiabatic" process means being adiabatic (no heat exchnage) at every instant of the process not just in the sense that the total heat exchange is zero. ... An isentropic process is by definition a process that is both adiabatic and reversible. So you can't have an isentropic process that is not adiabatic ... WebDec 4, 2024 · Isentropic process. In thermodynamics, an isentropic process is an idealized thermodynamic process that is adiabatic and in which the work transfers of the system are frictionless; there is no transfer of heat or of matter and the process is reversible. (2)(3)(4)(5)(6) Such an idealized process is useful in engineering as a model of and basis ...
