Oscillating stagnation point flow

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1982
Abstract 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 ...

Kinetics of polymer adsorption in stagnation point flow

Colloids and Surfaces, 1990
Abstract The kinetics of adsorption of poly(ethylene oxide) from water onto silica in stagnation point flow are studied using a reflectometric technique. It is shown that with reflectometry an absolute and continuous determination of the adsorbed mass per unit area can be obtained.

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 of a Blunt Body in Hypersonic Flow

Journal of the Aeronautical Sciences, 1957
The purpose of this paper is to present a method of calculation devised to yield all the important information on the symmetric inviscid hypersonic flow in the stagnation point region of a blunt body. The problem is the same as that considered by Hayes3 who used a slightly different approach.

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 ...

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.

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.

Three‐dimensional Hiemenz stagnation‐point flows

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2020
Abstract A 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.

Stagnation-point flows in a porous medium

Chemical Engineering Science, 2005
In this paper, we present non-linear exact and asymptotic solutions to a Navier–Stokes equation of Brinkman type proposed by Joseph et al. (Water Resour. Res. 18(4) (1982) 1049) for the flow in the stagnation-point laminar boundary layer on a cylinder or sphere if fibers of increasing concentration are uniformly added to a porous medium surrounding ...
