Decrease in entropy in a fluid flow - Physics Stack Exchange

Webentropy generation takes place, the quality of energy (i.e. the exergy) decreases [1]. This is a reality in any fluid flow process. In order to preserve the quality of energy in a fluid flow process or at least to reduce the entropy generation, it is important to study the distribution of the entropy generation within the fluid volume. WebMentioning: 2 - The effect of local thermal nonequilibrium (LTNE) on the entropy generation and heat transfer characteristics in the magnetohydrodynamic flow of a couple‐stress fluid through a high‐porosity vertical channel is studied numerically using the higher‐order Galerkin technique. The Boussinesq approximation is assumed to be valid and the … cryptographically synonym
