Abstract This study investigates molecular transfer within Bingham fluids, with an emphasis on optimizing thermal processes via exhaustive analytical and numerical approach. A slip boundary model is developed to effectively evaluate conditions at the interface between fluid solid. In order simplify analysis, governing equations are modeled assuming long wavelengths smaller Reynolds numbers for convection. Utilizing perturbation method, answer derived. Mathematica simulations cast light underlying mechanisms of mass transfer. The research highlights significant influence slide flow dynamics, heat rates, concentration distribution near interface. Various physical effects viscous dissipation‐related parameters utilized conduct a comprehensive analysis. indicates that circumstances, magnetic field intensity, number significantly velocity, temperature, profiles, heightened augmenting velocity diminishing volume trapped boluses. Moreover, transmission enhanced by dissipation buoyant forces, while profiles diminish increasing Schmidt, Soret, Brinkmann numbers. results this have practical implications optimization involving fluids contribute greater understanding in context.
