Heat Transfer Phenomenon for A Thermally Radiative Al2o3-Cu/ Water Based Hybrid Nanofluid Flow Past an Exponentially Stretched Porous Surface

Abstract

This research investigates the fluid dynamics and heat transfer characteristics of a hybrid nanofluid. The nanofluid flows over an exponentially expanding surface while releasing heat during the process. Additionally, the study considers heat transport and radiation effects. By employing similarity variables to transform (PDEs) into (ODEs), we can obtain similarity solutions. An implicit Finite Difference approach called Keller Box Method is employed to compute precise solutions to the problem.To provide a visual representation of the significance of various characteristics, we present graphical representations considering the relevant physical parameters. A notable discovery of this research is the consistent enhancement in heat transfer rates observed in hybrid nanofluids compared to conventional fluids. This increase in heat transfer rate is primarily influenced by the thermal radiation parameter within hybrid nanofluids. We also depict velocity and temperature profiles graphically, which are influenced by factors such as porosity and radiation. We explore the impact of varying thermophysical properties on velocity and temperature distributions, with a particular focus on the radiation parameter and Prandtl number. These graphical tools serve as a means to illustrate and elucidate the research findings and conclusions.
