Effects of Isentropic Efficiency and Enhancing Strategies.
In thermodynamics, an isentropic process is an idealized thermodynamic process that is both adiabatic and reversible. The work transfers of the system are frictionless, and there is no transfer of heat or matter. Such an idealized process is useful in engineering as a model of and basis of comparison for real processes.From the second law of thermodynamics, an isentropic process of liquids and solids is also an isothermal (constant temperature) process. Isentropic conditions also occur at stagnation points - a fluid condition defined by the point at which a flow is isentropically brought to zero velocity. (see: Pitot tube.) The Carnot cycle consists of two isentropic and two isothermal processes.An isentropic process is 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.
See Compressible flow, Entropy, Isentropic process. Because of the second law of thermodynamics, an isentropic flow does not strictly exist. From the definition of entropy, an isentropic flow is both adiabatic and reversible. However, all real flows experience to some extent the irreversible phenomena of friction, thermal conduction, and diffusion.Isentropic Process (rapid depressurization of a vessel) Background: Isentropic (reversible adiabatic) processes are often desired and are often the processes on which device efficiencies are based. One example of a process that approaches being isentropic is the rapid depressurization of gas in a cylinder.
Isentropic definition is - of or relating to equal or constant entropy; especially: taking place without change of entropy.
