Numerical and Analytical Solutions for Viscous Flow between Parallel disks in Different Nanofluids

We investigate the incompressible boundary layer viscous flow of fluids with nanoparticles between parallel disks. In this article, the set of the governing PDEs is reduced into system of coupled ODEs, which is then numerically solved by using Runge-kutta method. Effects of the various parameters such as thermal conductivity, volume fraction, and Prandtl number on velocity and heat transfer characteristics for different nanofluids containing Cu, Al2O3, TiO2 are analyzed. Also a comparative thermal behavior of the fluids has been discussed and presented presented through tables. It is found that the velocity profiles are enhanced by increasing the volume concentration of the nanoparticles and also the heat transport is improved. As a result, the momentum boundary layer thickness increases while the thermal boundary layer thickness becomes thinner.
