ENTROPY GENERATION ANALYSIS OF Al2O3–WATER NANOFLUID FLOW PAST A PERMEABLE CONE UNDER THE EFFECT OF SUCTION/INJECTION AND VISCOUS OHMIC DISSIPATIONS

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