Slip flow of an optically thin radiating non-Gray couple stress fluid past a stretching sheet

slip flow of an optically thin radiating non-gray couple stress fluid past a stretching sheet

this paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. the cogley- vincenti-gilles equilibrium model is employed to include the effects of thermal radiation in the study. the governing boundary layer equations are transformed into a system o...

Unsteady boundary layer flow of a Casson fluid past a wedge with wall slip velocity

In this paper an analysis is presented to understand the effect of non–Newtonian rheology, velocity slip at the boundary, thermal radiation, heat absorption/generation and first order chemical reaction on unsteady MHD mixed convective heat and mass transfer of Casson fluid past a wedge in the presence of a transverse magnetic field with variable electrical conductivity. The partial differential...

Momentum and Thermal Slip Flow of MHD Casson Fluid over a Stretching Sheet with Viscous Dissipation

Lie group analysis of magnetohydrodynamic tangent hyperbolic fluid flow towards a stretching sheet with slip conditions

In this paper, we studied MHD two dimensional flow of an incompressible tangent hyperbolic fluid flow and heat transfer towards a stretching sheet with velocity and thermal slip. Lie group analysis is used to develop new similarity transformation, using these similarity transformation the governing nonlinear partial differential equation are reduced into a system of coupled nonlinear ordinary d...

Uniqueness of Flow of a Second-order Fluid past a Stretching Sheet*

In [4], Rajagopal et al. use a perturbation analysis suggested by Beard and Walters [1] for boundary layer flows of non-Newtonian fluids. They consider a wall coinciding with the plane y = 0 and with the flow confined to y > 0. Two equal and opposite forces are applied along the jc-axis so that the wall is stretched while the origin remains fixed. The steady two-dimensional boundary layer model...

Flow of a Williamson Fluid over a Stretching Sheet

In the present article, we have examined the two dimensional flow of Williamson fluid model over a stretching sheet. The governing equations of pseudoplastic Williamson fluid are modelled and then simplified by using similarity transformations and boundary layer approach. The reduced equations are then solved analytically with the help of homotopy analysis method. The physical features of the m...
