Numerical study of MHD Williamson hybrid nanofluid flow over incessantly moving thin needle in presence of Soret & Dufour effect

This research presents a comparative analysis of Cross diffusion effect on 2D MHD chemical reactive Williamson hybrid nanofluid (MoS₂ − GO/Methanol) on a moving thin needle with thermal radiation. The main aim of this study is to increase the thermal efficiency using two different categories of nanoparticles: MoS₂ − GO, with Methanol serving as the original liquid is calculated. PDEs can be changed into ordinary differential equations with the help of similarity substitution. Which are nonlinear, and the bvp4c technique is used to numerically simplify it. The results of this investigation indicate that the velocity profile of GO/Methanol composite nanofluid increases more than that of MoS₂ − GO/Methanol through the increasing amount of Grashof number and Weissenberg parameter, even as the magnetic parameter and porosity impact have the opposite effect. On other hand, the chemical reaction and Schmidt number increase the rate of mass transfer for both nanofluids. The larger values of thermal radiation and Dufour effect enhance the thermal profile.
