Thermodynamic analysis of Powell-Eyring-blood hybrid nanofluid through vertical stretching sheet with interface slip and melting heat

Abstract

The present endeavor investigates the significance of entropy production due to stagnation point flow of hybrid nanofluid through a vertical stretchable surface. The system irreversibility arises due to fluctuation of temperature between mainstream and interface. At the surface of the sheet, the effects of slippage and melting are considered. The buoyancy-obsessed flow of hybrid mixture is exposed to Lorentz forces and thermal radiation. The mixture is created with the infusion of Iron and magnesium nanoparticles in Powell-Eyring fluid, which reassemble the blood features. The principal conservation equations (momentum and energy) are modified with the deployment of Tiwari-Das model. The resulting blood mixture demonstrates the features of shear thinning fluids. The prevailing boundary layer equations are turned into a system of ordinary differential equations by applying certain modifications, which are solved numerically by a Keller-Box approach for actual boundary conditions. Among the most intriguing results is that the volumetric loading of iron nanoparticles, melting phenomena, and slip provide a substantial thermal improvements. The flow of blood detract with escalation of melting and slippage at the boundaries. The effects of buoyancy assistance escalates the blood flow. Enlargement in viscosity parameter reduces the fluid viscosity and reduces the fluid drift. The effects of viscoelastic parameter are conflicting for velocity and temperature. The thermal profile escalates with increase in magnetic parameter. The production of entropy increases with enhanced Lorentz and buoyancy forces while diminished with slip and melting effects. The consequences of Bejan against theses parameters are conflicting. The frictional coefficient detract with high melting effects, while the results for energy transport coefficient are contrary. The influence of Iron are significant because of denser density.
