Effect of Varying Thermal Conductivity on MHD Micropolar Fluid Flow Based on Cattaneo-Christov Heat Flux Model over an Exponentially Extended Stretching Curved Surface

This study investigates the magnetohydrodynamic (MHD) flow of a micropolar fluid over an exponentially extended stretching curved surface. The boundary layer flow along with temperature-dependent thermal conductivity is also taken into account. The Cattaneo-Christov heat flux model is used for energy equation. The curvilinear coordinates are used in the formation of flow equations. The governing non-linear partial differential equations (PDEs) are transformed into coupled non-linear ordinary different equations (ODEs) by appropriate transformations. The resulting ODEs are solved numerically using the ND-solve method in Mathematica. Graphs are plotted to explore the impacts of key parameters on microrotation, temperature, and velocity. Results show that increasing curvature leads to higher velocity and lower temperature, with potential applications in polymer processing and waste treatment. A comparison has been made with the existing literature as a limited case of present study to validate the results.
