| Summary: | Nanofluids have significant potential to enhance thermal properties and are widely applied in various fields, including medical sciences, industrial cooling processes, hybrid engine design, electromechanical systems, nuclear reactors, vehicle temperature management, and the pharmaceutical industry. Carreau–Yasuda fluid model designed [49–50] experimentally for the investigating blood transport. This study examines the two-dimensional magnetohydrodynamic transport of Carreau–Yasuda nanofluids, driven by a complex ciliary wave in a curved channel lined with cilia. Mathematical formulation is based on well-established equations governing mass, momentum, energy, and concentration transport for this complex fluid system. The problem encompasses a range of physical phenomena, including velocity slip, a radially applied magnetic field, Joule heating, viscous dissipation with heat sources/sinks, Brownian motion, and thermophoresis. Lubrication theory is employed to simplify the fluid transport equations, thereby reducing the complexity of the problem. The complex system of equations is solved using the renowned BVP5C solver in MATLAB, and the numerical solutions are validated with an artificial neural network (ANN) model for accuracy. The findings reveal that implementing slip at the boundaries enhances nanofluid transport, while the curvature parameter exhibits the opposite effect. It is reported that thermal slip reduces the resistance to heat flow at the fluid–surface interface, allowing less heat to escape and thereby increasing the fluid temperature near the wall. In contrast, velocity slip diminishes the friction between the fluid and the surface, reducing shear-induced heating and leading to a decrease in temperature. The temperature of the nanofluid increases with the Prandtl number, while positive thermoviscosity acts to moderate or regulate this rise. Furthermore, the mass transfer phenomenon is enhanced by concentration slip and the random motion of nanoparticles, while it is suppressed by the effects of magnetic field and thermophoresis parameters. |
