Stagnation Point Flow with Complex Composition
The Physics of Fluids, 1968A previous study of the laminar boundary layer involving four inert species with widely different molecular weights but with a uniform external stream has been extended to describe such a boundary layer at an axisymmetric stagnation point. The transport properties of the gas mixture are described with reasonable accuracy so as to permit assessment of ...

Non-axisymmetric Homann stagnation-point flows
Journal of Fluid Mechanics, 2012Abstract A 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 ...

On the Creation of Stagnation Points in a Rotating Flow
Ocean Engineering, 1997Abstract 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.

Stagnation-point flow in a rotating cylinder
The Physics of Fluids, 1974Linear theory is used to study the pure stagnation-point flow created inside a rotating cylinder by introducing fluid uniformly through the top surface and removing it uniformly through the side wall. Of main interest is the completely new role played by the E1/2 layer at the side wall, although the (unsteady) E1/4 and E1/3 layers also have novel ...

Catalytic combustion in stagnation-point flow
Wärme- und Stoffübertragung, 1985Catalytic ignition and extinction processes are analyzed in this paper. The premixed fuel flows towards a catalytic plate of finite thermal conductivity and thickness. The effect of the external heating or cooling on these critical phenomena is also evaluated.

Unsteady axisymmetric stagnation point flow
Fluid Dynamics Research, 1992The 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.

Stagnation point flow in a diffusion cell
Chemical Engineering Science, 1983Abstract Stagnation point flow in a diffusion cell was examined to determine how close the resulting flow approached that produced under ideal conditions, and to evaluate its application to mass transfer systems. Ideal conditions exist when the substance can flow directly into a barrier, then reflect cleanly without the distortion of surrounding ...

ON THE VISCOUS FLOW NEAR THE STAGNATION POINT ON AN INTERFACE
1964Abstract : 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 ...
