WebThis paper is an extension of a previous work by the authors on developing a thermodynamic model that capture effectiveness of the Atkinson/Humphry cycle for power production. 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 or heat pump cycles by control…
