Work interaction in quasi-one-dimensional flows

Theoretical work addition is derived in a form analogous to that of classic al Rayleigh heat addition. From this derivation it Is evident that work ter ms can be added to the Navier-Stokes momentum and energy equations represen ting work interaction. A second-law-based effectiveness parameter controlli ng the ratio of realizable work interaction to the ideal work interaction i s required for nonideal analysis. Thus, the theoretical limits on work inte raction are parameterized, and a method is developed for easily modeling is entropic and nonisentropic work interaction in computational fluid dynamics . This fundamental theoretical approach is independent of the method employ ed for the work interaction, that is, turbomachinery, magnetohydrodynamics, etc....
