ABSTRACT

In this work, the transport phenomena of a hybrid ferrofluid over a non-linear stretching sheet and magnetohydrodynamic (MHD) boundary layer flow are investigated. The governing partial differential equations are converted into ordinary differential equations through similarity transformations. The ODES are tackled numerically by employing the shooting strategy in conjunction with MATLAB’s bvp4c solver. The study assesses the sensitivity of velocity, thermal, and concentration fields to changes in governing parameters, including the Weissenberg number, magnetic parameter, porous resistance, Darcy–Forchheimer parameter, power-law index, suction parameter, thermophoresis, radiation, Eckert number, Schmidt number and chemical reaction factor demonstrated through graphs in detail. The study concludes that magnetic, porous, Darcy-Forchheimer, Weissenberg, and suction effects reduce velocity while buoyancy and power-law behaviour increase it. Radiation, Brownian motion, thermophoresis, and the Eckert number all increase temperature fields, whereas heat absorption and a larger power-law index decrease them. Concentration decreases with increasing Schmidt number, Brownian diffusion, thermophoresis, and chemical reactions. Skin friction and Sherwood numbers decrease under magnetic, porous, and Weissenberg influences, while solutal buoyancy and the power-law index increase them. The numerical results correlate favourably to previous literature, demonstrating the model's robustness. These findings are especially useful for improving heat transfer, energy usage, and chemical engineering applications of hybrid ferrofluids.
