Unsteady Viscous Dissipative Dusty Nanofluid Flow Over a Vertical Plate

摘要

The flow past an infinite vertical isothermal plate started impulsively in its own plane in aviscous incompressible two-phase nanofluid has been considered by taking into account the viscousdissipative heat. Two nano particles Copper (Cu) and Alumina (Al2O3) are submerged in a base fluid,Water (H20). The coupled non-linear partial differential equations which govern the flow are solved fornanofluid and dust particle phases by finite difference method. The velocity and temperature fields havebeen shown graphically for various parameters. Here Grashof number, (Gr) being positive (cooling of theplate) for dusty air. Also the effects of Eckert number on heat transfer and skin friction coefficient forvarious parameters are represented graphically. It is observed that dusty nanofluid enhances both skinfriction and heat transfer rate in the case of cooling.
