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.

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.

Flow induced morphological instabilities: Stagnation-point flows

Journal of Crystal Growth, 1988
Abstract We consider a planar stagnation-point flow on a directionally-solidifying interface and determine its effects on its morphological instability. We find that when Schmidt numbers are large, two-dimensional long-wave disturbances are unstable for any degree of constitutional undercooling.

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 ...

Impinging rotational stagnation-point flows

International Journal of Non-Linear Mechanics, 2017
Abstract 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.

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.

Magneto-hydrodynamic asymmetric stagnation point flow

Journal of Physics D: Applied Physics, 1995
The nonlinear boundary layer equations of the title problem, which are also applicable to a low magnetic Prandtl number magneto-hydrodynamic (MHD) flow (e.g. a liquid metal), are solved using a reliable finite difference method for obtaining the coefficient of skin friction.

Viscous rotational stagnation-point flow

Journal of Fluid Mechanics, 1971
The investigation by Hayes (1964a) of the behaviour of a constant-density inviscid rotational flow in the neighbourhood of a stagnation point on a plane wall has been extended to include the effects of viscosity. The principal effect is the manner in which the singularity in vorticity discovered by Hayes is removed.

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

Oblique two-fluid stagnation-point flow

European Journal of Mechanics - B/Fluids, 1998
The authors study the impingement of two viscous, immiscible, oblique stagnation flows forming a flat interface. The two-dimensional motion of fluids is characterized by densities \(\rho_1\) and \(\rho_2\), by viscosities \(\mu_1\) and \(\mu_2\), and by asymptotic angles \(\vartheta_1\) and \(\vartheta_2\) of incident streamlines in each fluid layer ...
