Abstract
The fluid containing solid nanoparticles "nanofluid" performed more effectively compared to conventional fluids. The thermal scientists and scholars considered nanofluid in their research due to its useful applications in different thermal systems. But nanofluid still not enough for the required thermal transport properties. Therefore, the researchers tried to disperse two or more than two nanoparticles which are called hybrid and tri-hybrid nanofluid. It was tested experimentally that these hybrid nanofluids are more efficient fluids in different cooling systems compared to nanofluid and regular fluids. The present article carried out the research about the suspension of three different kinds of nanoparticles in various shapes for advance cooling applications in industries and engineering problems. The three nanoparticles are cylindrical carbon nanotubes(CNT)$( {CNT} )$, spherical aluminum oxide(Al2O3)$( {A{l_2}{O_3}} )$, and platelet shaped(Graphene) are mixed in water flowing in a rotating disk. This advance fluid has remarkable enhancement in the heat transfer rate in comparison with regular fluid, mono nanofluid and hybrid nanofluid. In this study viscoelastic radiative ternary hybrid nanofluid is considered on a rotating disk. The solutions are obtained by using the HAM method. For physical interpretation, all the flow parameters are discussed through graphs. The impact of volume fraction on the flow and heat transfer is also evaluated and presented in graphs. From the comparison, it was declared that tri-hybrid nanofluid has the best thermal performance compared to hybrid and mono nanofluid. Furthermore, radiation increases the temperature of the fluid, while viscoelastic parameter decreases the radial and tangential velocity. From the present study, we noticed that by considering the tri-hybrid mixture in water, the rate of heat transfer can be enhanced up to 33.69%. Finally, the results obtained show that the tri-hybrid nanofluid has excellent performance in the heat transfer rate.
