Thermodynamic Analysis of Hydromagnetic Micropolar Nanofluid Flow with Viscous Dissipation and Non-Uniform Heat Source in a Porous Channel

Abstract

The present study evaluates the flow and heat transfer dynamics of an electrically conducting micropolar nanofluid in the presence of microrotation, non-uniform heat source in a porous channel. The understanding of this phenomenon is indispensable in various engineering and manufacturing works, such as groundwater remediation in environmental engineering, enhanced oil recovery in petroleum engineering, design of heat exchangers in system cooling engineering, and so on. Thus, the current study explores hydromagnetic of heat-mass propagation in a non-Newtonian micropolar fluid that passing a porous channel, containing tiny microscopic nanoparticles. A mathematical model consisting of thermal radiative influence, temperature-dependent thermal conductivity, and subject to a non-uniform heat source is set up with engineered colloidal nanofluids dispersed in a base fluid using the Buongiorno model. The transformation of the model into ordinary differential equation form is achieved using suitable quantities, and the resultant model is solved numerically to derive the required solution for the transport phenomena. The results are communicated in figures and tables to show the influence of the embedded parameters on various dimensionless profiles of practical engineering applications. The results showed that the skin friction coefficient reduces as the micropolar parameter increases whereas the vortex viscosity term amplified the couple stress profile. There is a growth in the thermal field as the thermophoresis, Brownian motion, and Peclet numbers for mass and heat diffusion escalate in magnitude.
