Stagnation–saddle points and flow patterns in Stokes flow between contra-rotating cylinders [PDF]

open access: yes, 1998
The steady flow is considered of a Newtonian fluid, of viscosity mu, between contra-rotating cylinders with peripheral speeds U-1 and U-2 The two-dimensional velocity field is determined correct to O(H-0/2R)(1/2), where 2H(0) is the minimum separation of

On the hydrodynamics and heat convection of an impinging external flow upon a cylinder with transpiration and embedded in a porous medium [PDF]

open access: yes, 2017
This paper extends the existing studies of heat convection by an external flow impinging upon a flat porous insert to that on a circular cylinder inside a porous medium.

Stress singularities and the formation of birefringent strands in stagnation flows of dilute polymer solutions

open access: yes, 2009
We consider stagnation point flow away from a wall for creeping flow of dilute polymer solutions. For a simplified flow geometry, we explicitly show that a narrow region of strong polymer extension (a birefringent strand) forms downstream of the ...

The Stokes conjecture for waves with vorticity [PDF]

open access: yes, 2012
We study stagnation points of two-dimensional steady gravity free-surface water waves with vorticity. We obtain for example that, in the case where the free surface is an injective curve, the asymptotics at any stagnation point is given either by the “

Numerical investigation of magnetohydrodynamic stagnation point flow with variable properties

open access: yesAlexandria Engineering Journal, 2016
This article is concerned with the two-dimensional flow of Powell–Eyring fluid with variable thermal conductivity. The flow is caused due to a stretching cylinder. Temperature dependent thermal conductivity is considered.

Impinging Howarth stagnation-point flows

open access: yesEuropean Journal of Mechanics - B/Fluids, 2019
The flow of one Howarth stagnation-point flow impinging directly on another Howarth stagnation-point flow is studied, and an exact similarity solution to the Navier-Stokes equations is found. The upper layer fluid has density ρ1 and kinematic viscosity ʋ1 while the lower layer fluid has density ρ2 and kinematic viscosity ʋ2 and the two fluids are ...

A computer-controlled four-roll mill for investigations of particle and drop dynamics in two-dimensional linear shear flows [PDF]

open access: yes, 1986
In this paper we describe the design and operating characteristics of a computer-controlled four-roll mill for investigations of particle and drop dynamics in two-dimensional linear flows.

Theoretical Analysis of Groundwater Flow Patterns Near Stagnation Points

open access: yesWater Resources Research, 2019
The importance of stagnation points for characterizing groundwater flow patterns has long been recognized. However, the possible streamline configurations near stagnation points under the constraints of Darcy's law have not been thoroughly investigated ...

Stagnation point flow of viscoelastic nanomaterial over a stretched surface

open access: yesResults in Physics, 2018
Present communication aims to discuss magnetohydrodynamic (MHD) stagnation point flow of Jeffrey nanofluid by a stretching cylinder. Modeling is based upon Brownian motion, thermophoresis, thermal radiation and heat generation.

Compressible Flow Exfoliation of Two‐Dimensional Nanomaterials: Insights Into Layer Separation Informed by Gas Dynamics

open access: yesAdvanced Engineering Materials, EarlyView.
This study elucidates the mechanism of compressible flow exfoliation for producing 2D hexagonal boron nitride (h‐BN). Fluid dynamics analysis reveals that acceleration‐driven aerodynamic shear forces, rather than shock waves alone, drive effective layer separation.
