摘要

This research delves into the combined effects of magnetohydrodynamic (MHD) convection, Joule heating, and radiation on hybrid nanofluid flow within a porous medium between two parallel rotating disks. The study utilizes similarity transformations to convert partial differential equations (PDEs) into ordinary differential equations (ODEs), subsequently solving these equations using the Akbari Ganji Method (AGM). AGM is renowned for its robustness in addressing nonlinear problems. The study investigates how various factors influence speed, temperature, and concentration, with results depicted through graphs. The simultaneous effects of parameters on the skin friction coefficient, Nusselt number, and Sherwood number are examined using ANOVA analysis. The findings highlight that the temperature profile enhances with an increase in magnetic field strength (M), while the Nusselt number shows a positive correlation with the convective parameter (B1). Specifically, the Nusselt number Nux₁ increases as the M value rises. Conversely, an increase in B1 results in a decrease in Nux₁. Furthermore, the study reveals that the Sherwood number (Sh) increases concurrently with the Schmidt number (Sc) and the chemical reaction parameter (Cr).
