Three dimensional problem of steady nanofluid deposition on an inclined rotating disk is illustrated. The important effects of Brownian motion and thermophoresis have been included in the model of nanofluid. The basic partial differential equations are reduced to ordinary differential equations which are solved numerically using the fourth-order Runge–Kutta method. The numerical investigation is carried out for different governing parameters namely: Normalized thickness, Schmidt number, Brownian parameter and thermophoretic parameter. Results show that Nusselt number is an increasing function of each active parameter. Latent heat has direct relationship with Schmidt number, Brownian parameter and thermophoretic parameter but it has reverse relationship with Normalized thickness.
This article is made to examine the impact of external magnetic source on Fe3O4-water ferrofluid convective heat transfer in a porous cavity. The solutions of final equations are obtained by Control volume based finite element method (CVFEM). Graphs are shown for various values of Darcy number (Da), Fe3O4-water volume fraction (ϕ), Rayleigh (Ra) and Hartmann (Ha) numbers. Results indicate that augmenting in Hartmann number results in reduce in velocity of nanofluid and augment the thermal boundary layer thickness. Adding nanoparticles in the based fluid is more effective for higher values of Hartmann number and lower values of Darcy number.
