The primary aim of this study is to investigate the influence of a time-varying magnetic field on the unsteady slip flow of a ternary hybrid nanofluid over an inclined rotating disk, and to analyze the associated heat transfer mechanism. The hybrid nanofluid is composed of copper, titanium, and aluminium oxide suspended in water, serving as the base fluid. The heat transfer mechanism considered in this study comprises Joule heating and viscous dissipation. Results demonstrate that the inclusion of thermal radiation significantly enhances the heat transfer system and renders it more realistic under the effects of convection. The mathematical problem is defined by a set of non-linear partial differential equations and associated slip boundary conditions. Using a suitable similarity transformation, the proposed mathematical system is transformed into a system of nonlinear ordinary differential equations incorporating slip boundary conditions. Subsequently, the transformed equations are solved using the Homotopy Analysis Method (HAM). Graphs of the accurate results of the dimensionless velocity and temperature for various flow parameters provide a better understanding of the heat transfer characteristics of this system. It is observed that the influence of the magnetic reduces the heat transfer rate for stable non-zero slip. These findings have important implications for the design and optimization of heat transfer systems in engineering applications.
