Abstract
A model of fluid behaviour is proposed for both air and steam in Joule, Brayton, and Rankine cycles by assuming that enthalpy is a function of temperature only. This enables reheat to be treated in a unified manner for both gas and steam turbines. Theorems for maximum power and maximum thermal efficiency are presented, with extensions to inter-cooling in gas turbines and afterburners in turbo-jet craft.
