Homotopy Solution for Stagnation-Point Flow
Communications in Theoretical Physics, 2012This article reports the homotopy solution for stagnation point flow of a non-Newtonian fluid. An incompressible second grade fluid impinges on the wall either orthogonally or obliquely. The resulting nonlinear problems have been solved by a homotopy analysis method (HAM). Convergence of the series solutions is checked. Such solutions are compared with

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

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.

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 of Rarefied GaS
Journal of the Physical Society of Japan, 1967This paper deals theoretically with the stagnation-point flow of a rarefied gas. Representative Mach number M S taken in the continuum flow region is assumed to be small and thus the analysis is based on the linearized B-G-K equation. A method of solution is developed in which the continuum flow and the Knudsen layer flow are considered successively ...

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 ...

Impinging rotational stagnation-point flows
International Journal of Non-Linear Mechanics, 2017Abstract A rotational stagnation-point flow of fluid density ρ1 and kinematic viscosity ν1 impinges normal to another rotational stagnation-point flow of fluid density ρ2 and viscosity ν2. Results are compared with a previous study on the normal impingement of two Homann stagnation-point flows for which the flow in the far field is irrotational.
