Stagnation‐point Flow in Magnetohydrodynamics

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1967
AbstractThe inviscid three‐dimensional stagnation‐point in magnetohydrodynamics is investigated in full generality. The analytic character of the flow depends on just two parameters, one of which characterizes the streamline pattern on the body and the other the effective interaction of the electromagnetic field. The pattern, according to linear terms,

Unsteady stagnation point flow

Applied Scientific Research, 1972
In this paper we consider the changes in the two-dimensional stagnation point flow against a plane wall when the wall is impulsively set in motion in its own plane. In particular a solution which describes the final approach to the ultimate steady state is determined.

Oscillating stagnation point flow

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1982
A solution of the Navier-Stokes equations is given for an incompressible stagnation point flow whose magnitude oscillates in time about a constant, non-zero, value (an unsteady Hiemenz flow). Analytic approximations to the solution in the low and high frequency limits are given and compared with the results of numerical integrations. The application of

Stagnation - Point Solution

1981
The boundary layer at three-dimensional stagnation points has been the object of many theoretical investigations. Since a review on the literature available is not intended, only a few references are mentioned here [40,53,68]. HOWARTH [40]was one of the first to present results for a general three-dimensional stagnation point.

MIXED CONVECTION AT A STAGNATION POINT

The Quarterly Journal of Mechanics and Applied Mathematics, 1995
Summary: We are concerned with the mixed convective flow at a two-dimensional stagnation point on a heated horizontal boundary. The forced flow may be a stagnation-point flow of either forward or rear type, and the free convective element is due to a pressure gradient that is induced by temperature variations along the boundary.

Blood rheology near a stagnation point

Biorheology, 1982
Blood rheology at a stagnation point is studied in views of microhemorheology. Special emphasis is put on the effect of both non-Newtonian and unhomogeneous properties of blood on the fine structure of blood flow impinging on the wall. It is shown that “non-flow” region exists just at the stagnation point due to the non-Newtonian viscosity when its ...

Stagnation Point Combustion of a Monopropellant

AIAA Journal, 1981
The steady-state stagnation point transport and reaction equations describing premixed monopropellant combustion have been investigated approximating the chemical processes by an endothermic solid-phase pyrolysis and a one-step exothermic unidirectional gas-phase reaction.

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 ...
