Blood rheology near a stagnation point

Biorheology, 1982
Blood rheology at a stagnation point is studied in views of microhemorheology. Special emphasis is put on the effect of both non-Newtonian and unhomogeneous properties of blood on the fine structure of blood flow impinging on the wall. It is shown that "non-flow" region exists just at the stagnation point due to the non-Newtonian viscosity when its ...

Rotational stagnation point flow

Journal of Fluid Mechanics, 1964
The constant-density inviscid rotational flow in the neighbourhood of a general stagnation point on a wall is investigated. In all but very special cases, the solution is non-analytic and the vorticity at the wall is infinite; the stagnation streamline is tangent to the wall at the stagnation point; stagnation points of saddlepoint type cannot exist ...

On the Creation of Stagnation Points in a Rotating Flow

Ocean Engineering, 1997
Abstract We report the results of a numerical study of the creation of stagnation points in a rotating cylinder of fluid where both end-walls are rotated. Good agreement is found with previous results where the stagnation points are formed on the core of the primary columnar vortex.

Axisymmetric stagnation point flow in magnetohydrodynamics

Applied Scientific Research, Section B, 1961
This paper contains a theoretical treatment of the axisymmetric stagnation point problem in magnetohydrodynamics. Two distinct arrangements of the magnetic field are considered, with the lines of force lying in the plane of, and perpendicular to the streamlines, respectively.

Surface Reaction Near a Stagnation Point

Studies in Applied Mathematics, 2000
To measure rate constants while performing biomolecular interaction analysis (BIA), scientists often use resonant mirror devices such as the IAsysTM. A full mathematical model of the IAsysTM consists of a convection–diffusion equation in a closed well with a reacting surface at the bottom.

Periodic steady vortices in a stagnation-point flow

Journal of Fluid Mechanics, 1994
A stagnation point flow of the form U = (0, Ay, — Az) is unstable to three-dimensional disturbances. It has been shown that the vorticity components of such a disurbance that are perpendicular to the direction of the diverging flow will decay, and that the parallel component of vorticity can grow.

The unsteady oblique stagnation point flow

The Physics of Fluids, 1985
An exact solution of the unsteady Navier–Stokes equations is found. The solution describes the stagnation region of an accelerating circular jet impinging obliquely on a flat plate.

Viscous rotational stagnation-point flow

Journal of Fluid Mechanics, 1971
The investigation by Hayes (1964a) of the behaviour of a constant-density inviscid rotational flow in the neighbourhood of a stagnation point on a plane wall has been extended to include the effects of viscosity. The principal effect is the manner in which the singularity in vorticity discovered by Hayes is removed.

Theory of the Stagnation-Point Langmuir Probe

The Physics of Fluids, 1960
A theory is developed for a Langmuir-type probe consisting of a collecting electrode placed at the stagnation point of a blunt body immersed in a supersonic partially ionized stream. It is shown that under certain conditions, the stagnation-point boundary layer equations and the probe sheath equations can be solved together to yield potential vs ...
