Entropy Generation Analysis for a Micropolar Fluid Flow in an Annulus

摘要

The present article investigates the entropy generation of micropolar fluid flow between two circular cylinders. The fluid flow in an annulus is due to the rotation of the outer cylinder with constant velocity. The two cylinders are maintained at different constant wall temperatures. A numerical solution using spectral quasi-linearisation method is obtained. The effect of coupling number, Brinkman number and Reynolds number on the fluid velocity, microrotation, temperature profile, entropy generation rate and Bejan number are represented graphically and analysed quantitatively.
