Measurements in the vicinity of a stagnation point

Experimental Thermal and Fluid Science, 2002
Abstract This paper presents measurements of a plane jet impinging onto a normal flat plate placed up to five jet widths from the jet outlet. The small spacing ensured that the stagnation streamline remained in the potential core of the jet. The plate shear stress distribution compared well to that from an analytical solution for the laminar ...

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 ...

Stagnation - Point Solution

1981
The boundary layer at three-dimensional stagnation points has been the object of many theoretical investigations. Since a review on the literature available is not intended, only a few references are mentioned here [40,53,68]. HOWARTH [40]was one of the first to present results for a general three-dimensional stagnation point.

Oscillating stagnation point flow

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1982
A solution of the Navier-Stokes equations is given for an incompressible stagnation point flow whose magnitude oscillates in time about a constant, non-zero, value (an unsteady Hiemenz flow). Analytic approximations to the solution in the low and high frequency limits are given and compared with the results of numerical integrations. The application of

Unsteady flow at a stagnation point

Journal of Fluid Mechanics, 1993
The flow at an axisymmetric stagnation point is considered when the outer, inviscid flow is oscillatory with zero mean. It is shown that following the commencement of the flow at an initial instant there is a breakdown of the solution, after a finite time, as fluid erupts from the boundary at the stagnation point.

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.

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.

A note on oblique stagnation-point flow

Physics of Fluids, 2008
Previous analyses of oblique stagnation-point flow at a plane wall are discussed and unified with reference to a free parameter. The oblique flow consists of orthogonal stagnation-point flow to which is added a shear flow whose vorticity is fixed at infinity.

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 ...
