Simulation of the dynamics of colloidal mixture of water with various nanoparticles at different levels of partial slip: Ternary-hybrid nanofluid

Some of the fundamental properties of nanofluids capable of influencing not only the transport phenomena, but also mass and heat transfer within the boundary layer and throughout the domain are thermo-migration and random mobility of nanoparticles in the based fluid. In such a case mentioned above, nothing is known on a comparative ternary-hybrid nanofluid flows induced by forced convection, free convection, and mixed convection when radiative heat flux is substantially regulated by temperature difference as in the case of non-linear thermal radiation, and partial slip. This report presents the similarity solutions of the governing equations that models the dynamics of colloidal mixture of water with spherical carbon nanotubes, cylindrical graphene, and platelet alumina nanoparticles at different levels of partial slip considering the cases of forced, free and mixed convection. The shooting approach was used in conjunction with the conventional Runge-Kutta integration scheme and MATLAB bvp4c to get solutions of the emerged boundary value problems. The outcome of the study shows that the friction at the wall decreases with partial slip but the most minimum decreasing rate manifests at the higher level of buoyancy forces when the transport phenomenon was induced by free convection. Optimal increasing transfer rates of mass/species is achievable due to rising haphazard motion of the three kinds of nanoparticles when the ternary-hybrid nanofluid was induced by mixed convection. Rising thermomigration of spherical carbon nanotubes, cylindrical graphene, and platelet alumina nanoparticles causes the transfer of species and heat across the ternary-hybrid nanofluid to diminish.

Automated summary

This study investigates the flow characteristics of ternary-hybrid nanofluids and their influence under temperature difference, nonlinear thermal radiation, and partial slip. The results show that partial slip reduces the friction at the wall, with the lowest decreasing rate observed in free convection. When induced by mixed convection, the increased motion of the three types of nanoparticles leads to optimal mass and heat transfer rates.
