THERMODYNAMICS ISENTROPIC EFFICIENCIES OF STEADY FLOW DEVICES

Irreversibilities accompany all actual processes and that their effect is always to
downgrade the performance of devices. In engineering analysis, it would be desirable
to quantify the degree of degradation of energy in these devices turbines,
compressors and nozzles. In order to do this we must identify and define an ideal
process that will serve as a model for the actual processes.
An ideal device would be adiabatic and have no irrevesibilities i.e. an isentropic
device. The parameter than expresses how efficiently an actual device approximates
an idealized one is called isentropic or adiabatic efficiency.
The isentropic efficiencies of each device is discussed separately for each device.
