Stagnation-point flow in a rotating cylinder

The Physics of Fluids, 1974
Linear 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 ...

Stagnation-Point Radiation for Apollo 4

Journal of Thermophysics and Heat Transfer, 2004
The radiative heating rate at the stagnation point of the Apollo 4 vehicle is calculated using an up-to-date set of radiation parameters and is compared with the flight data. The radiation parameter set includes the recently characterized atomic lines of N and O and the molecular bands of N 2 , CO, and H 2 in the vacuum ultraviolet wavelength range ...

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.

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.

Catalytic combustion in stagnation-point flow

Wärme- und Stoffübertragung, 1985
Catalytic 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.

Instability of stagnation points in magnetohydrodynamic equilibria

Physics of Plasmas, 1996
Instabilities associated with streamlines connecting stagnation points in an equilibrium with plane incompressible flow are studied. It is shown that they belong to two different types: If the velocity of fluid absorption at the endpoint is greater than the velocity of fluid emission at the initial point, only a discrete spectrum of unstable standing ...

Stability of stagnation points in rotating flows

Physics of Fluids, 1997
The Lifschitz and Hameiri theory for short-wave instabilities is used to show that any steady inviscid plane flow subjected (or not) to a Coriolis with perpendicular angular velocity vector is unstable to three-dimensional perturbations if Φ(x0)<0 on a stagnation point located at x0.

Homotopy Solution for Stagnation-Point Flow

Communications in Theoretical Physics, 2012
This 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

Stagnation point flow in a diffusion cell

Chemical Engineering Science, 1983
Abstract 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 ...
