摘要

The current study examines the magnetic field impact on the three-dimensional motion of Casson nanoliquid via a revolving stretchable surface with the porous media. The impact of thermal radiation, chemical reaction, heat source/sink, joule heating, and viscous dissipation on the fluid motion is also considered. Experts and engineers may increase the efficacy of chemical reactions or heat transportation processes by examining how reactions affect flow and designing systems with improved flows. The non-linear governing partial differential equations (PDEs) of the fluid flow problem are transformed into dimensionless ordinary differential equations (ODEs) with the similarity variables. Further, the obtained ODEs are solved numerically with the aid of Runge Kutta Fehlberg’s fourth-fifth order (RKF-45) approach. The influence of different factors on the various profiles is depicted using the visual representation. As the porosity and magnetic parameters increases, the velocity profile declines. For higher values of Casson fluid parameter, the velocity profile decreases. The increase in values of the radiation parameter, heat source/sink (HSS) parameter, and Eckert number enhances the thermal profile.
