Mixed convection flow of couple stress nanofluid over oscillatory stretching sheet with heat absorption/generation effects

Blog Article

The aim of this article is to highlight the unsteady mixed convective couple stress nanoliquid flow passed through stretching surface.The flow is generated due to periodic oscillations of sheet.An appropriate set of dimensionless variables are used Cubicles to reduce the independent variables in governing equations arising from mathematical modeling.An analytical solution has been computed by employing the technique of homotopy method.The outcomes of various sundry parameters like couple stress parameter, the ratio of angular velocity to stretching rate, thermophoresis parameter, Hartmann number, Prandtl number, heat source/sink parameter, Schmidt number described graphically and in tabular form.

It is observed that the velocity profile increases by increasing mixed convection parameter and concentration buoyancy parameter.The temperature enhances for larger values of Hartmann number Pop! Town and Brownian.The concentration profile increases by increasing thermophoresis parameter.Results show that wall shear stress increases by increasing couple stress parameter and ratio of oscillating frequency to stretching rate.Keywords: Oscillatory surface, Couple stress fluid, Nanoparticles, Heat absorption/generation.
