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 flow at a stagnation point

Journal of Fluid Mechanics, 1993
The flow at an axisymmetric stagnation point is considered when the outer, inviscid flow is oscillatory with zero mean. It is shown that following the commencement of the flow at an initial instant there is a breakdown of the solution, after a finite time, as fluid erupts from the boundary at the stagnation point.

Stagnation Points in Flows about Solid Bodies

Journal of Engineering Mathematics, 1999
The authors study two- and three-dimensional flows about solid bodies. In the two-dimensional case they consider the flows about a vortex pair and a dipole pair. Then the irrotational motion about two dipoles is considered in the three-dimensional case.

Stagnation-point flows in a porous medium

Chemical Engineering Science, 2005
In this paper, we present non-linear exact and asymptotic solutions to a Navier–Stokes equation of Brinkman type proposed by Joseph et al. (Water Resour. Res. 18(4) (1982) 1049) for the flow in the stagnation-point laminar boundary layer on a cylinder or sphere if fibers of increasing concentration are uniformly added to a porous medium surrounding ...

Heat transport and stagnation‐point flow of magnetized nanoliquid with variable thermal conductivity, Brownian moment, and thermophoresis aspects

Heat Transfer, 2020
The improvement of heat transport is a very important phenomenon in nuclear reactors, solar collectors, heat exchangers, and coolers, which can be achieved by choosing the nanofluid as the functional fluid.

Stagnation Point Flow With Suction: An Approximate Solution

Journal of Applied Mechanics, 1994
We present an approximate solution to the problem of the laminar two- dimensional flow of an incompressible, viscous fluid impinging on a wall from which the fluid is extracted at a uniform rate.

Study of three dimensional stagnation point flow of hybrid nanofluid over an isotropic slip surface

, 2020
A three dimensional axisymmetric stagnation flow of hybrid nanofluid impinges on a moving plate with different slip coefficients in two orthogonal directions. On the solid boundary, no slip condition is replaced through the partial slip condition.

Entropy generation on EMHD stagnation point flow of hybrid nanofluid over a stretching sheet: Homotopy perturbation solution

Physica Scripta, 2020
The intention of this article is to explore the entropy generation in EMHD hybrid nanofluid on a stagnation point in the presence of slips, heat generation and viscous dissipation. The fluid in the enclosure is water containing hybrid nanoparticles Ag-Cu.
