Features of the exponential form of internal heat generation, Cattaneo-Christov heat theory on water-based graphene-CNT-titanium ternary hybrid nanofluid flow

To increase energy efficiency, the flow of fluids containing nanoparticles is crucial in industrial applications notably in nuclear reactors and nuclear system cooling. In light of this, this study examines the flow of a water-based ternary hybrid nanofluid (graphene, single-walled carbon nanotubes, and titanium dioxide) across a curved stretching sheet with suction. The non-Fourier heat flux model is also considered in the modeling. The existing partial differential equations are converted into ordinary differential equations through the use of similarity variables. These ordinary differential equations are then numerically solved using the Runge-Kutta-Fehlberg fourth- and fifth-order method along with a shooting approach. The collection of graphical findings for the key variables on the temperature and velocity profiles is investigated. Results reveal that the heat transport in ternary hybrid nanoliquid rises as the heat source/sink parameter rises. The Biot number influences the thermal profile positively, whereas the increasing curvature parameter values reduce heat transport. The curvature parameter has a positive impact on skin friction but the suction parameter has a negative impact on skin friction.

Automated summary

This study investigates the flow of a water-based ternary hybrid nanofluid on a curved stretching sheet and explores the effects of key parameters on the temperature and velocity profiles. The results indicate that increasing the heat source/sink parameter enhances the heat transport in the nanoliquid, while increasing curvature parameter values reduce heat transport.
