Impact of Shape Dependent Ternary Hybrid Nanoliquid Flow through a Microchannel with Quadratic Thermal Radiation: Irreversibility Analysis

Abstract

The elite implementations of the trihybrid nanoliquid are converting solar thermal energy, photovoltaic heat collectors, and power storage. This work explores the irreversibility analysis in an upright microchannel subjected to convective ternary hybrid nanoliquid flow with quadratic thermal radiation. The consequences of the Darcy Forchheimer rule, heat source coefficient, and no slip condition on the thermal performance are studied. In the base liquid engine oil, the three distinct types of nanoparticles having different shapes including spherical (Ti), cylindrical (MgO) and platelet (Cu) configurations were considered in this scrutiny. The combined model is used to approach trihybrid and hybrid nanoliquid thermophysical properties. The governing partial differential equation is transferred into the ordinary differential equation by employing dimensionless terms. In the next step to solve the ordinary differential equations, the RKF45 numerical technique is used. The acquired upshots divulge that the improved temperature parameter strongly supports the flow profile. Thermal profile inflates with increased Darcy number. The entropy production shows dual behaviour for the escalated quadratic radiation parameter. With an enhanced darcy number of 400%, the entropy generation rises by 14% in the ternary hybrid nanoliquid circumstances and rises by 11% in the hybrid nanoliquid situation. In addition, when the combination of spherical, cylindrical, and platelet nanoparticles is considered the rate of thermal transfer is greater compared to spherical and cylindrical nanoparticle combinations.
