The Brayton cycle, also known as the Joule cycle, is a thermodynamic cycle that describes the operation of certain heat engines that have air or some other gas as their working fluid. It is characterized by isentropic compression and expansion, and isobaric heat addition and rejection, though practical engines have adiabatic rather than ...
The most common refrigeration cycle is the vapor compression cycle, which models systems using refrigerants that change phase. The absorption refrigeration cycle is an alternative that absorbs the refrigerant in a liquid solution rather than evaporating it. Gas refrigeration cycles include the reversed Brayton cycle and the Hampson–Linde cycle.
English: T-S diagram for a Brayton Cycle. Solid line shows an ideal cycle, dotted line a real one. Solid line shows an ideal cycle, dotted line a real one. 1) compressor inlet 2) compressor outlet 3) turbine inlet 4) turbine outlet C) compressor B) combustion chamber
Differs from Otto cycle in that V 1 < V 4. Brayton: adiabatic: isobaric: adiabatic: isobaric Ramjets, turbojets, -props, and -shafts. Originally developed for use in reciprocating engines. The external combustion version of this cycle is known as the first Ericsson cycle from 1833. Diesel: adiabatic: isobaric: adiabatic: isochoric Diesel engine ...
The basic scheme of the IBC and temperature-enthalpy diagram are presented in figures 1 and 2. [4] For external heat sources or high temperature storage systems, the closed process design of the inverted Brayton Cycle is also possible. The overall efficiency can thus be significantly increased. [5]

A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, [1] [2] etc.) for the working fluid as part of a closed thermodynamic ...

By routing its exhaust gases into a heat exchanger for a turbine Brayton cycle or steam generator Rankine cycle, MHD can convert fossil fuels into electricity with an overall estimated efficiency of up to 60 percent, compared to the 40 percent of a typical coal plant. A magnetohydrodynamic generator might also be the first stage of a gas core ...
