Investigation of Darcy Forchheimer (DF) phenomena on the heat transfer in radiated nanofluid using SWCNTs nanomaterial

The purpose of this research is to investigate the enhanced thermal transport in hybrid (C 2 H 6 O 2 /H 2 O) by utilizing SWCNTs and joint contribution of internal and external physical constraints like solar radiations, heating source, Forchheimer effects and unsteady flow phenomena. The flow of SWCNTs/(C 2 H 6 O 2 /H 2 O) is taken over a sphere which rotates about its axis. Further, formulation is accomplished by operating the similarity transformative functions and then achieved the results using bvp4c scheme. It is examined that the unsteady and Forchheimer effects enhance the fluid flow while the NPs concentration controls it due to increasing density and viscosity factor. The unsteady number diminishes the velocity G ( η ) , while Forchheimer number increases it. The use of externally acting radiations and internally contributing heat source provided significant increase in the thermal performance of SWCNTs/(C 2 H 6 O 2 /H 2 O). Further, the rate of heat transfer improves by augmenting concentration. Furthermore, the unsteady number also favors the Nusselt number and observed augmentation. The output would be beneficial for thermal applications, electronics cooling and heat exchangers when the considered physical configuration occur.
