| Summary: | This work addresses the three-dimensional flow of hybrid nanofluid owing to a rotating disk of variable thickness in the attendance of modified Fourier law. The hybrid nanofluid is comprised of gold and silver nanoparticles and engine oil taken as the base fluid. The heat transfer impact is analyzed in the employment of melting heat transfer. To analyze the traits of the fluid flow, Tiwari and Das model is utilized. The strongly non-linear system of governing equations is handled through the appropriate similarity transformations to obtain the coupled differential equations’ system that is solved numerically using the bvp4c scheme. The physiognomies of numerous parameters versus the radial and tangential velocities and heat transfer are depicted via graphs and cogitated accordingly. It is witnessed that the velocity and the heat transfer of the hybrid nanofluid flow possesses a substantial impact in comparison to the nanofluid. It is inferred from this that the performance of the hybrid-nanofluid is far better than the common nanofluid. The current findings are compared to those of a previously published study in a limiting case. A reliable agreement between the numeric values is achieved here. |
