Analysis of Micro-Hybrid and Casson-Hybrid Nano-Convective and Radiative Fluid Flow in an Inclined Channel

Abstract

The underlying intension of this study is to oversee the entropy generation due to Casson-micropolar hybrid nanofluid flow in an inclined microchannel. Magnesium oxide (MgO) and Zirconium oxide (ZrO2) nanoparticles are considered with a base fluid of polyethylene glycol (PEG). The proposed system of nonlinear differential equations is numerically solved with a shooting procedure (R-K 4th order). Outcomes obtained for the velocity f (ζ), the micro rotation g (ζ), the Bejan number Be, the Entropy generation Ns, and the temperature distribution θ (ζ) are elucidated via graphs. A comparative study of obtained results with previously published results are also discoursed. One of the interesting outcomes of this study is found to be—an increase in the radiation reduces the fluid temperature at the center of the microchannel and the Bejan number profiles postulate that the heat transfer irreversibility dominates around the center of the microchannel.
