Natural Convection Past Inclined Porous Layers
Journal of Applied Mechanics, 1982This paper describes a study of combined Rayleigh-Be´nard convection and Tollmien-Schlichting type of instability of a fluid in an inclined layer bounded by two permeable beds. Several types of flows, depending on the value of the Prandtl number, Pr, are studied using a fast convergent power series technique.

Convective Phenomena in Mushy Layers
Annual Review of Fluid Mechanics, 2020Since the Annual Review of Fluid Mechanics review of mushy layers by Worster (1997) , there have been significant advances in the understanding of convective processes in mushy layers. These advances have come in the areas of ( a) more detailed analysis, computation, and understanding of convective instabilities and chimney convection in binary alloys;

Buoyancy is the dominant mechanism driving turbulence in a convective boundary layer. Such turbulence is not completely random, but is often organized into identifiable structures such as thermals and plumes (Young, 1988). Entertainment happens at a variety of scales: lateral entertainment by small eddies into the sides of thermals, and vertical ...

Thermal convection in laminar Boundary layers II
Applied Scientific Research, 1953The heat loss of a hot body with constant surface temperature by thermal convection in a laminary boundary layer is described by partial differential equations. These can only be reduced to ordinary differential equations if the temperature and velocity profiles at any two points are similar. This leads to a geometrical condition that is given here for

Steady Convection in Deep Compressible Layers
Astrophysics and Space Science, 1998It is known from the literature that the standard mixing-length model of convection traditionally used in astrophysics is based on an analogy with the kinetic theory of gases. Simulations of steady convection do not find eddies of order of local scale height, but rather single cells extending over several scale heights from top to bottom of the layer ...

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

Photoadaptation in a convective layer
Deep Sea Research Part II: Topical Studies in Oceanography, 1999Measurements of Lagrangian trajectories acquired with neutrally buoyant floats in an upper ocean mixing layer during a five-day period of nearly cloudless and calm conditions, provide an opportunity for investigating the implications of photo-adaptation of phytoplankton exposed to varying light intensities as they traverse the water column in ...

Convection in Horizontal Layers
1977Our third example of fluid motion in a simple configuration is taken from a different branch of fluid mechanics, free convection. The cause of motion is the action of a gravitational field on the density variations associated with temperature variations — essentially the well-known fact that hot fluid rises.
