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 ...

Unsteady axisymmetric stagnation point flow

Fluid Dynamics Research, 1992
The unsteady axisymmetric case of a three-dimensional stagnation flow is investigated. The incompressible potential flow far away from the stagnation point oscillates about a constant mean value. Using perturbation methods, an analytical solution of the problem is obtained for the extreme cases of low and high oscillation frequencies.

AN UNSTEADY STAGNATION-POINT FLOW

The Quarterly Journal of Mechanics and Applied Mathematics, 1989
We consider the oscillatory flow at a two-dimensional stagnation point. We show, following the initiation of the motion, that the solution always develops a singularity at a finite time, and we discuss the implications of this for the flow over a cylinder which performs transverse harmonic ...

Unsteady Stagnation Point Heat Transfer

Journal of Heat Transfer, 1965
An analysis is presented for the unsteady laminar, forced-convection heat transfer at a two-dimensional and axisymmetrical front stagnation due to an arbitrarily prescribed wall temperature or heat flux variation. The flow is incompressible and steady.

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.

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.

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 heat flow meter

Journal of Scientific Instruments, 1965
An instrument is described with which the energy transfer from a stream of reacting or non-reacting gases can be measured. By employing recent stagnation point, convective heat transfer theory, the enthalpy can be determined at any position in a stream of high enthalpy gases.
