    The study of magnetohydrodynamic (MHD) boundary layer flow over melting surfaces embedded in Darcy–Forchheimer porous media is essential for improving thermal management in industrial processes such as metal casting, polymer extrusion, and geothermal heat extraction. This research numerically investigates the combined effects of chemical reaction, thermal radiation, viscous dissipation, and Forchheimer inertial resistance on the velocity, temperature, and concentration distributions within an electrically conducting fluid flowing over a moving, melting surface. Assuming an incompressible Newtonian fluid and employing similarity transformations, the governing equations are formulated based on the conservation of mass, momentum, energy, and species concentration. The resulting system of nonlinear ordinary differential equations (ODEs) is solved using a shooting method in conjunction with the fourth-order Runge–Kutta scheme. Overall, the proposed numerical model effectively captures the interplay of magnetic, thermal, and chemical effects, offering valuable insights for the design of efficient thermal systems involving melting processes and porous structures.

    This study seeks to analyse the magnetohydrodynamic (MHD) flow of a nanofluid, focussing on heat and mass transfer in nano liquids over a stretchable surface near a stagnation point, while considering changeable thermal conductivity. The thermal behavior of the suspended nanoparticles is found to be significantly affected by Brownian motion. The influence of the chemical responses well as the continuous inner warmth source or washbasin are in addition taken into account. The governing equations are changed into a system of coupled ordinary differential equations utilising an appropriate similarity transformation. The computational software PYTHON is employed to address the boundary value problem (BVP) utilising the shooting method. The numerical results are supported by the online PYTHON software function bvp4c. The numerical results are derived by varying the values of the physical parameters associated with the flow problem. The results are presented in graphical and tabular formats. As the thermal energy of the liquid increases, the thermophoresis values trend upward, while the Nb values show a downward trajectory. Also, we found that the response rate encourages a reduction in the thermal boundary layer's thickness.
