Compressibility and free convection
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1966Abstract 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 ...

Turbulence in helium-gas free convection
Physical Review A, 1989Results 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.

Magnetohydrodynamic free convection
Journal of Fluid Mechanics, 1964The 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.

Visualizations of instabilities in free convection plumes
Journal of Visualization, 2009Flow 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 Convection in a Rectangular Cavity (Benard Convection) With Nanofluids
Heat Transfer, Volume 3, 2004Investigators 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 ...

Free-Convection Heat Transfer in Screened Greenhouses
Journal of Agricultural Engineering Research, 1998Free-convection heat transfer between heating pipes and air, horizontal screen and air and inner roof surface and air was studied experimentally in twin-span glasshouses, under constant heat flux conditions. Among other results, equation coefficients between Nusselt and Rayleigh numbers are presented for the inner surface of the greenhouse roof, screen

A ‘BACKWARD’ FREE-CONVECTIVE BOUNDARY LAYER
The Quarterly Journal of Mechanics and Applied Mathematics, 1981In 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
