On Polyekthetic Processes

Abstract

This Preprint introduces polyekthetic processes, a generalization of polytropic processes. The etymology of the new term is given, and the concept is explained theoretically. A useful associated definition for constant-property processes, for arbitrary properties and expressions thereof, is given, and associated polyekthetic exponents k_ijℓ are defined and a general solution is obtained. Examples on van-der-Waals, general, and ideal gas substances are provided with discussions.
