Numerical investigation of nanofluid spraying on an inclined rotating disk for cooling process

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.
