Abstract
The study of melting heat transfer in micropolar nanofluid flow through porous media can provide insights into optimizing various industrial and engineering processes, as well as improve our understanding of fluid transport through porous media in environmental and biomedical applications. This study focuses on the impact of Brownian motion, thermophoresis, internal heat generation/absorption, chemical reaction and melting effects on two-dimensional micropolar nanofluid flow across a permeable stretchy surface with a stagnation point. Appropriate similarity transformations are chosen in order to convert the system of the nonlinear ordinary differential equation. The results for various parameters are examined by applying the shooting method with BVP5C technique. Furthermore, graphs and tables are used to explore the impact of significant factors that affected the velocity, microrotation, thermal behavior, and concentration of nanofluids. Results reveals that the increase in values of Brownian motion and thermophoresis parameters caused a growth in the Sherwood number and drop in the Nusselt number. The upshot of the stretching parameter (SP) on velocity, temperature, concentration and microrotation is studied. Results reveal that the velocity and microrotation fields remain constant while thermal activity increases for SP[Formula: see text][Formula: see text][Formula: see text]1. The higher value of the SP increases the concentration.
