Gas turbine thermodynamics
WebThe entropy of a given mass does not change during a process that is internally reversible and adiabatic. A process during which the entropy remains constant is called an isentropic process, written = or =. Some examples of theoretically isentropic thermodynamic devices are pumps, gas compressors, turbines, nozzles, and diffusers.. Isentropic efficiencies of … WebThermodynamics of gas turbine cycles. A.M.Y. Razak, in Industrial Gas Turbines, 2007. 2.4. Steady flow energy equationUnlike a piston engine, where the compression and expansion processes are intermittent, the gas turbine cycle is a continuous flow process.
