Optimization of thermal transfer in Casson hybrid nanofluids with magnetohydrodynamics and activation energy effects

Abstract

Enhanced heat transfer is still a major challenge in many engineering industries in the modern era including advanced cooling systems and material processing techniques. There have been past researches in the effects of magnetohydrodynamics (MHD), Casson fluids and nanofluid flows, however, there is not much that has been done to investigate the combined effects of these factors in a hybrid nanofluid system while incorporating activation energy, Hall effect and current parameters. Through investigating the inextricable connections between these parameters, the current study introduces a novel approach by employing unified model regarding the aforementioned hybrid Casson nanofluid flow over a stretching sheet. The methodology used in the research consists of transforming the non-linear higher order partial differential equations which represent the fluid behavior into first order linear ordinary differential equations through similarity transformation and using the Runge Kutta 4th order method in conjunction with the shooting technique for numerical analysis. This points out the special role of magnetic and Casson parameters in tangential velocity and reveals the effect of the Hall and current effect on the velocity and temperature profiles. The study also shows the potential of hybrid nanofluids in enhancing the performance of thermal management systems. Besides supplementing an important gap in the current literature, this research provides unique insights to potentially propel innovations in industrial contexts where efficient heat transfer and fluid flow are essential.
