Abstract

A wide range of technological and industrial domains, including heating processors, electrical systems, mechanical systems, and others, are facing issues as a result of the recent developments in heat transmission. Nanofluids are a novel type of heat transfer fluid that has the potential to provide solutions that will improve energy transfer. The current study investigates the effect of a magnetic field on the two-dimensional flow of Williamson nanofluid over an exponentially inclined stretched sheet. This investigation takes into account the presence of multi-slip effects. We also consider the influence of viscous dissipation, thermal radiation, chemical reactions, and suction on the fluid’s velocity. We convert the nonlinear governing partial differential equations (PDEs) of the fluid flow problem into dimensionless ordinary differential equations (ODEs) through the utilization of similarity variables. We then use the homotopy analysis method (HAM) to numerically solve the resulting ordinary differential equations (ODEs). We demonstrate the effects of numerous elements on a variety of profiles through graphical and tabular representations. We observe a drop in the velocity profile whenever we increase either the magnetic number or the suction parameter. Higher values of the Williamson parameter lead to an increase in the thermal profile, while the momentum of the flow displays a trend in the opposite direction. The potential applications of this unique model include chemical and biomolecule detection, environmental cleansing, and the initiation of radiation-induced chemical processes like polymerization, sterilization, and chemical synthesis.
