AN EVAPORATION HEAT ENGINE AND CONDENSATION HEAT PUMP [PDF]

open access: yesThe ANZIAM Journal, 2008
AbstractThis paper presents a thermodynamic model for a heat engine based on evaporative cooling of unsaturated air at reduced pressure. Also analysed is a related heat pump based on condensation of water vapour in moist air at reduced pressure. These devices operate as two-stroke reciprocating engines, which are their simplest possible embodiments ...

Information Arbitrage in Bipartite Heat Engines

open access: yesPhysical Review X
Heat engines and information engines have each historically served as motivating examples for the development of thermodynamics. While these two types of systems are typically thought of as two separate kinds of machines, recent empirical studies of ...
