Simple microfluidic stagnation point flow geometries. [PDF]
Biomicrofluidics, 2016 A geometrically simple flow cell is proposed to generate different types of stagnation flows, using a separation flow and small variations of the geometric parameters. Flows with high local deformation rates can be changed from purely rotational, over simple shear flow, to extensional flow in a region surrounding a stagnation point. Computational fluid

Stagnation-point combustion with radiation [PDF]
Symposium (International) on Combustion, 1981 The relatively simple character of diffusion flames in laminar stagnation-point flows has led to numerous theoretical and experimental studies of that system. Here, as a first step toward incorporating radiation in analyses eventually related to fire safety, a grey radiating diffusion flame, above a grey pyrolyzing solid fuel is considered.

Oscillatory Flow Near a Stagnation Point [PDF]
SIAM Journal on Applied Mathematics, 2003 The authors consider an unsteady version of classical Hiemenz solution describing incompressible two-dimensional stagnation point flow at a solid wall, examining particularly the response close to the wall when the solution at infinity is modulated in time by a periodic factor of specified amplitude and frequency for arbitrary values of these ...

Inertioelastic Flow Instability at a Stagnation Point [PDF]
Physical Review X, 2017 A number of important industrial applications exploit the ability of small quantities of high molecular weight polymer to suppress instabilities that arise in the equivalent flow of Newtonian fluids, a particular example being turbulent drag reduction.

Stagnation point von Kármán coefficient [PDF]
Physical Review E, 2009 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)

Evolution of disturbances in stagnation-point flow [PDF]
Journal of Fluid Mechanics, 1994 The evolution of three-dimensional disturbances in an incompressible three-dimensional stagnation-point flow in an inviscid fluid is investigated. Since it is not possible to apply classical normal-mode analysis to the disturbance equations for the fully three-dimensional stagnation-point flow to obtain solutions, an initial-value problem is solved ...

On the Circulation and the Position of the Forward Stagnation Point on Airfoils [PDF]
International Journal of Mechanical Engineering Education, 2007 Lift and velocity circulation around airfoils are two aspects of the same phenomenon when airfoils are not stalled and the Kutta—Joukowski theorem applies. This theorem establishes a linear dependence between lift and circulation, which breaks when stalling occurs. As the angle of attack increases beyond this point, the circulation vanishes. Since the

Size Specific Trapping at a Convergent Stagnation Point [PDF]
Biophysical Journal, 2013 DNA has been observed to be trapped at a convergent stagnation point created by opposite rotating vortices in simulations based on the lattice-Boltzmann method using a bead-spring model for the DNA. Previous work has successfully separated polymers whose length differs by a factor of 2.

Impinging Howarth stagnation-point flows
European 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 ...
