The steam so produced is injected into the gas turbine's combustion chamber to increase power output. [3] The process can be thought of as a parallel combination of the gas turbine Brayton cycle and a steam turbine Rankine cycle. [4] [5] The cycle was invented by Prof. Dah Yu Cheng of the University of Santa Clara who patented it in 1976. [6] [1]
Two primary classes of thermodynamic cycles are power cycles and heat pump cycles. Power cycles are cycles which convert some heat input into a mechanical work output, while heat pump cycles transfer heat from low to high temperatures by using mechanical work as the input. Cycles composed entirely of quasistatic processes can operate as power ...

A Brayton cycle that is driven in reverse uses work to move heat. This makes it a form of gas refrigeration cycle. When air is the working fluid, it is known as the Bell Coleman cycle. [20] It is also used in the LNG industry for subcooling LNG using power from a gas turbine to drive the compressor. [dubious – discuss] [citation needed]
The first and second law of thermodynamics are the most fundamental equations of thermodynamics. They may be combined into what is known as fundamental thermodynamic relation which describes all of the changes of thermodynamic state functions of a system of uniform temperature and pressure.

In fact, all thermodynamic potentials are expressed in terms of conjugate pairs. The product of two quantities that are conjugate has units of energy or sometimes power. For a mechanical system, a small increment of energy is the product of a force times a small displacement. A similar situation exists in thermodynamics.
