Abstract
The current investigation considers the unsteady two-dimensional MHD flow along with heat and mass transfer of Williamson nanofluid over a moving cylinder of a porous medium. The influence of chemical reactions, thermal radiation, and Joule heating are also considered. This article will use the Buongiorno model to explore the Brownian motion heat transfer process and thermophoresis. The boundary layer governing equations is made non-dimensional by employing the usual transformation. To solve the non-linear dimensionless governing equations, a technique known as the explicit finite difference method (EFDM) is used. A stability analysis was carried out to make the approach more convergent, and an efficient criterion (Le≥0.018 and Pr≥0.03) was obtained. The influence of different parameters on the velocity, temperature, and concentration profile are illustrated graphically. From this study, we have achieved that the increase in radiation raises the temperature of the boundary layer region. Also, it was found that the speed of the hybrid nanofluid can be controlled by applying a magnetic field and porous media and enhancing Williamson parameters. To validate the accuracy of the numerical scheme, a qualitative comparison of the results obtained is made with that of the previously published works.
