ENTROPY GENERATION ANALYSIS OF AL2O3–WATER NANOFLUID FLOW PAST A PERMEABLE CONE UNDER THE EFFECT OF SUCTION/INJECTION AND VISCOUS OHMIC DISSIPATIONS

A hydromagnetic nanofluid flow past a permeable cone with heat and mass transfer has been investigated. An incompressible, steady, laminar flow was used to study the entropy generation. The main aim was to find the physical parameters responsible for the enhancement of the entropy generation. The presence of nanoparticles in a base fluid helps to improve the heat transfer characteristics. Based on the obtained results, we can predict the entropy variation due to the variation in the flow parameters. The enhancement in the slip velocity and suction/ injection parameters is shown to enhance the system efficiency. It was found that the enhancement of diffusion leads to maximum irreversibility and minimum efficiency. The MATLAB built in bvp4c solver technique was used to solve transformed ordinary differential equations with convective boundary conditions.
