| description | Abstract This study presents a comprehensive investigation into the convective heat and mass transfer characteristics of non-Newtonian fluids, specifically Casson, Maxwell, and Williamson fluids, flowing along a vertical cone under the influence of magnetic fields and chemical reactions. Non-Newtonian fluids are widely utilized in industrial and automotive thermal management systems due to their superior thermal performance characteristics. The mathematical formulation accounts for magnetohydrodynamic effects, homogeneous chemical reactions, and transport phenomena associated with thermophoresis and Brownian motion. The governing equations, derived from the conservation laws of mass, momentum, energy, and species concentration, are reduced to a system of nonlinear ordinary differential equations through the application of similarity transformations. These equations are solved numerically using the BVP4C solver in MATLAB. A detailed parametric study is conducted to analyze the influence of key physical parameters on the velocity, temperature, and concentration distributions. The results indicate that the presence of a magnetic field decreases the fluid velocity due to the Lorentz force, while the thermophoretic and Brownian motion effects enhance the thermal and concentration boundary layers, leading to improved heat and mass transfer rates. Chemical reaction parameters are observed to significantly modify the concentration profiles.The findings contribute to a deeper understanding of non-Newtonian fluid behavior and offer guidance for the design of efficient thermal systems. |
