Second-law analysis of fluid flow over an isothermal moving wedge
Alexandria Engineering Journal, 2014 In this study, entropy generation minimization (EGM) was employed to optimize fluid flow and heat transfer over a moving wedge. Governing partial differential equations including continuity, momentum and energy are reduced to ordinary ones using ...

Entropy Generation via Ohmic Heating and Hall Current in Peristaltically-Flowing Carreau Fluid
Entropy, 2019 The core objective of the present study is to examine entropy generation minimization via Hall current and Ohmic heating. Carreau fluid considerations interpret the unavailability of systems’ thermal energy (for mechanical work).

A mathematical model for entropy generation in a Powell-Eyring nanofluid flow in a porous channel
Heliyon, 2019 The continuous generation of entropy leads to exergy destruction which reduces the performance of a physical system. Hence, entropy minimization becomes necessary.
