Analysis of heat transfer using Local thermal non‐equilibrium conditions for a non‐Newtonian fluid flow containing Ti6Al4V and AA7075 nanoparticles in a porous media

Abstract

AbstractThe accurate forecasting of thermal processes is one of the primary concerns of those working in the area of heat transfer as well as those in the energy research community. The present investigation makes use of a simplified mathematical model as an illustration in order to investigate the properties of heat transport under the lack of local thermal equilibrium conditions. The LTNE model results in two distinct primary thermal gradients, one for the fluid phase and another for the solid phase. The non‐Newtonian fluid flow containing Ti6Al4V and AA7075 nanoparticles with a base fluid sodium alginate over a stretching sheet in a porous media with magnetic effect is studied here. The shooting approach is used to transform the resultant equations of boundary value problems into initial value problems, which are subsequently solved using Runge–Kutta–Fehlberg 45 process. The impact of pertinent parameters on the involved fields have been discussed graphically. Results reveal that the increase in porosity and magnetic parameters value decreases velocity and increases thermal performance. An upsurge in inter‐phase heat transfer parameter increases the heat transport rate of solid phase but, decreases the liquid phase heat transport rate.
