Dynamics of Alumina Nanofluid with Different Ratios of EG-Water Mixture (Base Fluid): Effect of Slip Flow Under Lorentz Force

Nanofluids hold great promise in revolutionizing heat transfer applications and offer many advantages compared to conventional heat transfer fluids. Their superior thermal properties, adjustability, stability and potential for energy conservation make them an appealing option for various engineering and industrial processes. This, in turn, paves the way for the development of more efficient and sustainable technologies in the future. Flow formulation is developed in this study by considering the effect of magnetic field, thermal radiation and oscillatory flow in a porous medium through asymmetric wavy channel. The primary objective of this research is to determine the thermal and physical characteristics of a \(Al_2O_3\) (alumina) nanofluid composed of three cases. Specifically, three different volume ratios of EG to water were considered: 0:100%, 20:80% and 50:50%. To describe this system mathematically, the governing equations are transformed into non-linear partial differential equations using appropriate dimensionless transformations. These equations are subsequently solved analytically. As a result of these calculations, graphical representations of velocity, temperature, and concentration profiles, Skin Friction Coefficient, Heat and Mass transfer rate are generated. The study highlighted the significance of radiative heat transfer by analysing temperature and Nusselt number variations with changes in the thermal radiation parameter. The 20:80% EG-Water ratio exhibited the highest velocity, followed by 0:100% EG-Water and 50:50% EG-Water base fluid. This highlights the dependence of flow characteristics on the composition of the nanofluid. Temperature profiles revealed a significant temperature spike in the 20:80% EG-Water ratio compared to the balanced 50:50% ratio.
