Magnetohydrodynamic Unsteady Free Convection

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1967
AbstractThe unsteady free convection flow from an infinite vertical plate, under the action of a transverse magnetic field, is analysed in the case when the plate temperature undergoes a thermal transient. The solution is obtained by Laplace transform technique. The applied field is found to induce a wave‐dominated flow pattern.

Magnetohydrodynamic free convection

Journal of Fluid Mechanics, 1964
The flow of an electrically conducting fluid up a hot vertical plate in the presence of a strong magnetic field normal to the plate is considered. A solution is developed based on the idea of matching ‘outer’ and ‘inner’ solutions in the moving layer of fluid.

Compressibility and free convection

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1966
Abstract The basic equations of laminar compressible flow and heat transfer are applied to the free convection boundary layer along an isothermal plate. Solutions which include the effect of all the parameters involved are given. It is found that in the complete approach, the profiles can not be expressed in terms of one similarity ...

Natural or Free Convection

2015
As opposed to a forced convection flow where external means are used to provide the flow, the free-convection flow field is a self-sustained flow driven by the presence of a temperature gradient.

A note on free convection

Boundary-Layer Meteorology, 1973
The limiting condition of µ*, →0 in the unstable atmospheric boundary layer is usually referred to as ‘free convection’. Some of the similarity laws that are proposed for this condition do not agree with experiment. A mechanism is proposed in this paper to show why the asymptotic free convection condition is never completely reached near the surface ...

Turbulence in helium-gas free convection

Physical Review A, 1989
Results on a Rayleigh-B\'enard experiment in helium gas at 5 K in a cylindrical cell of aspect ratio 1 are presented. The Rayleigh number spans a range from ${10}^{5}$ to ${10}^{12}$. A large-scale coherent flow is observed via the correlation of two adjacent temperature probes.

Visualizations of instabilities in free convection plumes

Journal of Visualization, 2009
Flow visualization techniques1,2,3 were employed to investigate vortex instabilities in free convection plumes (Fig. 1) as well as in the interaction of opposite buoyancy-induced flows (Figs 2,3). Visualizations were carried out by means of laser tomography combined with the electrolytic precipitation method2 (Figs 1,3) and the dye fluorescent ...

Free Penetrative Convection

1986
Free penetrative convection is the disorganized movement without a mean velocity created by a source of buoyancy flux flowing into an ambient fluid.

Free Convection in a Rectangular Cavity (Benard Convection) With Nanofluids

Heat Transfer, Volume 3, 2004
Investigators have been surprised with new thermal phenomena behind the recently discovered nanofluids, fluid with unprecedented stability of suspended nanoparticles although huge differences in the density of nanoparticles and fluid. For example, nanofluids have anomalously high thermal conductivities at very low volume fraction, strongly temperature ...
