Abstract

Heat transfer technology is quickly increasing as a result of the demand for well-organised heating and cooling systems (HGS and CGS) in the necessary chemical, automotive, and aerospace sectors. Thus, the current study aims to observe mixed convective flow of a Williamson fluid near the stagnation point in the presence of hybrid nanoparticles (Al2O3 and Cu) across a vertical flat plate with the Hall effect. The water-based alumina (Al2O3) and copper (Cu) nanoparticles that have been convectively heated are evaluated for their suitability in industry. The primary equations are non-dimensionalized employing the relevant similarity factors before being solved numerically by the bvp4c solver in MATLAB software. We examine the impacts of several pertinent parameters on transverse and axial velocities, drag force, temperature, and heat transfer. In the case of opposing flow, two different outputs are obtained, whereas just one is procured in the case of assisting flow. The impact of Lorentz force can also be used to alter the flow and physical properties of heat transfer.
