Nested separatrices in simple shear flows: the effect of localized disturbances on stagnation lines [PDF]
The effects of localized two-dimensional disturbances on the structure of shear flows featuring a stagnation line are investigated. A simple superposition of a planar Couette flow and Moffatt's [J. Fluid Mech.

A stagnation-point flow of a Powell–Eyring nanofluid along a vertical stretching surface is examined. The buoyancy force effect due to mixed convection is taken into consideration along with the Brownian motion and thermophoresis effect.

Stagnation point von Kármán coefficient [PDF]
On the basis of various direct numerical simulations (DNS) of turbulent channel flows the following picture is proposed. (i) At a distance y from either wall, the Taylor microscale lambda is proportional to the average distance l(s) between stagnation points of the fluctuating velocity field, i.e., lambda(y)=B(1)l(s)(y) with B(1) constant, for delta(nu)

Analytic Adjoint Solutions for the 2D Incompressible Euler Equations Using the Green's Function Approach [PDF]
The Green's function approach of Giles and Pierce is used to build the lift and drag based analytic adjoint solutions for the two-dimensional incompressible Euler equations around irrotational base flows. The drag-based adjoint solution turns out to have a very simple closed form in terms of the flow variables and is smooth throughout the flow domain ...

Stagnation-point flow past a shrinking sheet in a nanofluid. [PDF]
In this paper, the stagnation-point flow and heat transfer towards a shrinking sheet in a nanofluid is considered. The nonlinear system of coupled partial differential equations was transformed and reduced to a nonlinear system of coupled ordinary ...

The present work highlights the stagnation point flow with mixed convection induced by a Riga plate using a Cu-Al 2 O 3 /water hybrid nanofluid. The electromagnetohydrodynamic (EMHD) force generated from the Riga plate was influential in the heat ...

Vortex shedding in a two-dimensional diffuser: theory and simulation of separation control by periodic mass injection [PDF]
We develop a reduced-order model for large-scale unsteadiness (vortex shedding) in a two-dimensional diffuser and use the model to show how periodic mass injection near the separation point reduces stagnation pressure loss.

Reactions between the highly strained uranacycle I with various boranes afford unprecedented uranium complexes bearing either a pendant borate or a pendant borane Lewis acid. The latter promotes the 1,2‐insertion of CO into a UIV‐N bond. Abstract In this contribution, we illustrate uranium complexes bearing a pendant borate (i.e.

MHD oblique stagnation-point flow of a Newtonian fluid [PDF]
The steady two-dimensional oblique stagnation-point flow of an electrically conducting Newtonian fluid in the presence of a uniform external electromagnetic field (E0, H0) is analyzed, and some physical situations are examined.
