Hybrid nanofluid flow through a spinning Darcy-Forchheimer porous space with thermal radiation

This work investigates numerically the solution of Darcy-Forchheimer flow for hybrid nanofluid by employing the slip conditions. Basically, the fluid flow is produced by a swirling disk and is exposed to thermal stratification along with non-linear thermal radiation for controlling the heat transfer of the flow system. In this investigation, the nanoparticles of titanium dioxide and aluminum oxide have been suspended in water as base fluid. Moreover, the Darcy-Forchheimer expression is used to characterize the porous spaces with variable porosity and permeability. The resulting expressions of motion, energy and mass transfer in dimensionless form have been solved by HAM (Homotopy analysis method). In addition, the influence of different emerging factors upon flow system has been disputed both theoretically in graphical form and numerically in the tabular form. During this effort, it has been recognized that velocities profiles augment with growing values of mixed convection parameter while thermal characteristics enhance with augmenting values of radiation parameters. According to the findings, heat is transmitted more quickly in hybrid nanofluid than in traditional nanofluid. Furthermore, it is estimated that the velocities of fluid f' (xi), g(xi) are decayed for high values of phi(1), phi(2), Fr and k(1) factors.

Automated summary

This study numerically investigates the solution of Darcy-Forchheimer flow for hybrid nanofluid using slip conditions. It is found that velocity profiles increase with higher values of mixed convection parameter, while thermal characteristics enhance with increasing values of radiation parameters. This indicates that heat is transmitted more quickly in hybrid nanofluid than in traditional nanofluid.
