Hybrid Nanofluids Flows Determined by a Permeable Power-Law Stretching/Shrinking Sheet Modulated by Orthogonal Surface Shear

Bimodal diffusion in power-law shear flows.

The phenomenon in which a Brownian particle moves faster than diffusively arises in a number of diverse situations. In the context of fluid mechanics [1-3], for example, a dynamically neutral tracer particle in a linear shear flow, with fluid velocity ~v(x, y) ∝ yx̂, exhibits a mean-square longitudinal displacement which grows in time as 〈x(t)〉 ∼ t. It is also well-known that the probability dis...

Gravity-Driven Flow of a Shear-Thinning Power– Law Fluid over a Permeable Plane

The flow of a thin layer of power-law fluid on a porous inclined plane is considered. The unsteady equations of motion are depth-integrated according to the von Karman momentum integral method. The variation of the velocity distribution with the depth is accounted for, and it is furthermore assumed that the flow through the porous medium is governed by the modified Darcy’s law. The stability co...

Peristaltic transport of a power-law fluid in an asymmetric channel bounded by permeable walls

In this paper peristaltic transport of a power law fluid in an asymmetric channel bounded by permeable beds is studied under long wavelength and low Reynolds number assumptions. The channel asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase due to the variation of channel width, wave amplitudes and phase differences. Expressions for t...

Mixed Convection Boundary Layer Flows Induced by a Permeable Continuous Surface Stretched with Prescribed Skin Friction

The boundary layer flow and heat transfer on a stretched surface moving with prescribed skin friction is studied for permeable surface. The surface temperature is assumed to vary inversely with the vertical direction x for n = -1. The skin friction at the surface scales as (x) at m = 0. The constants m and n are the indices of the power law velocity and temperature exponent respectively. Simila...
