Entropy generation due to micropolar fluid flow between concentric cylinders with slip and convective boundary conditions

Abstract

Abstract In this study, the entropy generation of micropolar fluid flow through concentric cylindrical annulus associated with slip and convective boundary conditions is performed numerically. The fluid flow in an annulus is due to the rotation of the outer cylinder with constant velocity. The analysis of such kind of fluid flow is governed by nonlinear partial differential equations. In the present study these equations are solved using the spectral quasilinearization method. The resultant velocity, microrotation and temperature distributions from the spectral quasi linearization method are used to evaluate the entropy generation rate and the Bejan number. Further the impact of boundary conditions on the entropy generation is also presented.
