| Summary: | Many viscoelastic fluid problems are solved using the notion of fractional derivative. However, most
researchers paid little attention to the effects of nonlinear convective in fluid flow models with timefractional derivatives and were mainly interested in solving linear problems. Furthermore, the nonlinear
fluid models with a fractional derivative for an unsteady state are rare, and these constraints must be
overcome. On the other hand, nanofluids are thought to be trustworthy coolants for enhancing the cooling process in an electrical power system. Therefore, this research has been conducted to analyze the
unsteady upper-convected Maxwell (UCM) hybrid nanofluid model with a time-fractional derivative.
Incorporating the Cattaneo heat flux into the energy equation has increased the uniqueness of the
research. The numerical solutions for the coupled partial differential equations describing velocity and
temperature are presented using an efficient finite difference method assisted by the Caputo fractional
derivative. Significant changes in heat transfer and fluid flow properties due to governing parameters,
including the nanomaterial volume fraction, fractional derivative, relaxation time, and viscous dissipation, are graphically demonstrated. The nanomaterial concentration, the fractional derivative parameter,
and the relaxation time parameter must all be substantial to manifest a surface heat increase. |
