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.

Free Convection Grid Turbulence

1989
The idea of a velocity of convection of turbulent velocity and temperature fluctuations stems originally from TAYLOR’s work on grid turbulence (1). If the turbulence level were low, the time variation of the velocity \( \overrightarrow U \), observed at a fixed point in the flow would be approximately the same as those due to the convection of an ...

Magnetohydrodynamic Free-Convection Pipe Flow

Journal of the Aerospace Sciences, 1961
Comparison of Flow-Direction Probes at Supersonic Speeds FRANK W. BARRY 750 I HAS BEEN SHOWN 1 tha t transverse magnetic fields of practica strengths exert considerable influence on liquid-metal, freeconvection, vertical, flat-plate and parallel-plate flow fields.

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.

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.

Compressibility and free convection

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1966
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 variable and one parameter ...

Low Prandtl-number free convection

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1958
Eine Untersuchung der freien Konvektion wurde an einer senkrechten isothermen Platte bei Prandtlscher Zahl im Bereiche von 0,003–0,03 (das heisst flussige Metalle) durchgefuhrt. Dabei wurden zahlenmassige Losungen der laminaren Grenzschichtgleichungen erhalten.

A ‘BACKWARD’ FREE-CONVECTIVE BOUNDARY LAYER

The Quarterly Journal of Mechanics and Applied Mathematics, 1981
In this paper the cooling of a low-heat-resistance sheet that moves downwards is considered. The free-convective velocities are assumed to be much larger than the velocity of the sheet. As a result the motion of the fluid is mainly towards the point where the sheet enters the system and a ‘backward’ boundary layer ensues. It is shown that the equations

Advances in Free Convection

1967
Publisher Summary This chapter focuses on the advances in free convection. The average treatise on heat transfer dismisses free convection in a single chapter. It is, nevertheless, potentially as large a subject as forced convection and has developed rapidly within the last decade.
