Dynamic of Two-phase Dusty Nanofluid Flow Past a Vertical Wavy Surface

Abstract

An analysis is performed to study two-phase natural convection flow with heat transfer of nanofluid along a vertical way surface. The model includes equations expressing conservation of total mass, momentum and thermal energy for two-phase nano fluid. Primitive variable formulations (PVF) are used to transform the dimensionless boundary layer equations into convenient coordinate system and resulting equations are integrated numerically via implicit finite difference iterative scheme. The effects of the controlling parameters on the dimensionless quantities such as skin friction coeffcient, rate of heat transfer and rate of mass transfer are explored. It is concluded from present analysis, that the diffusivity ratio parameter, NA and particle-density increment number, NB has pronounced effect in reduction of heat transfer rate.
