 Entropy generation in a micropolar fluid flow through an inclined channel with slip and convective boundary conditionsD. Srinivasacharya and K. Hima Bindu Energy, 2015, vol. 91, issue C, 72-83 Abstract: The present paper studies the entropy generation in a micropolar fluid flow through an inclined channel with slip and convective boundary conditions. The governing equations are linearized using quasi-linearization and then solved using Chebyshev spectral collocation method. The velocity, microrotation and temperature profiles are obtained and utilized to compute entropy generation and Bejan number. The effects of the angle of inclination, coupling number, slip parameter, Biot number and Brinkman number on the velocity, microrotation, temperature, entropy generation and Bejan number are studied and presented graphically. The results reveal that the entropy generation number increases with the increase of angle of inclination and Brinkman number while the increase of coupling number and Reynolds number causes the entropy generation to reduce. It is observed that the heat transfer irreversibility dominates at the centre of the channel.
