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.

Three‐dimensional Hiemenz stagnation‐point flows

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2020
AbstractA modification of Hiemenz's two‐dimensional outer potential stagnation‐point flow of strain rate a is obtained by adding periodic radial and azimuthal velocities of the form and , respectively, where b is a shear rate. This leads to the discovery of a new family of three‐dimensional viscous stagnation‐point flows depending on the shear‐to ...

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 ...

Stagnation Points in Flows about Solid Bodies

Journal of Engineering Mathematics, 1999
The authors study two- and three-dimensional flows about solid bodies. In the two-dimensional case they consider the flows about a vortex pair and a dipole pair. Then the irrotational motion about two dipoles is considered in the three-dimensional case.

Stagnation Point Flow With Suction: An Approximate Solution

Journal of Applied Mechanics, 1994
We present an approximate solution to the problem of the laminar two- dimensional flow of an incompressible, viscous fluid impinging on a wall from which the fluid is extracted at a uniform rate.

Non-axisymmetric Homann stagnation-point flows

Journal of Fluid Mechanics, 2012
AbstractA modification of Homann’s axisymmetric outer potential stagnation-point flow of strain rate $a$ is obtained by adding periodic radial and azimuthal velocities of the form $b\hspace{0.167em} r\sin 2\theta $ and $b\hspace{0.167em} r\cos 2\theta $, respectively, where $b$ is a shear rate.

ON THE VISCOUS FLOW NEAR THE STAGNATION POINT ON AN INTERFACE

1964
Abstract : The viscous flow near the stagnation point on an interface between two liquids with different densities is studied. The use of a model allows some fairly general results to be readily obtained as a result of a mathematical analysis. Moreover, although the model is obviously not in full accordance with re-entry phenomena, it is believed that ...

MHD stagnation-point flow

2013
The flow near a stagnation-point is a fundamental topic in fluid dynamics and it has been studied by several researches during the past decades because of its relevant applications. In this Thesis we investigate the influence of the electromagnetic field on the stagnation-point flow of a Newtonian or a micropolar fluid.
