Convective Plumes in a Convective Field

Journal of the Atmospheric Sciences, 1970
Abstract The theory of isolated turbulent plumes given earlier is used to study a field of plumes. Each plume is immersed in the turbulent downdraft which comprises the return flow. The field of flow is specified by three parameters: the heat flux into the atmosphere at the surface, the depth of the convecting layer, and the intensity of turbulence at ...

Random convection

Journal of Fluid Mechanics, 1970
The main thrust of this work is to treat the initial convective phase of a fluid heated from below as a statistical initial value problem. The advantage of the approach is that it allows a continuous bandwidth of modes to be represented in the initial spectrum.

Preconditioning convection dominated convection‐diffusion problems

International Journal of Numerical Methods for Heat & Fluid Flow, 1995
This paper is concerned with the numerical solution of multi‐dimensional convection dominated convection‐diffusion problems. These problems are characterized by a large parameter, K, multiplying the convection terms. The goal of this work is the development and analysis of effective preconditioners for iteratively solving the large system of linear ...

Conduction and Convection [PDF]

, 1991
As we discussed in Chapter 8, our knowledge of the pore-level fluid mechanics in two-phase flow through porous media is rather incomplete. In this chapter, we discuss thermal dispersion, i.e., convective heat transfer at the pore level, using the available knowledge about the subject. This knowledge is even more inconclusive.

Diffusion and convection of heat in a dipole convection field

Mathematical Proceedings of the Cambridge Philosophical Society, 1970
AbstractThe problem of the diffusion and convection of heat from an arbitrarily placed source in the convection field due to a fluid producing dipole is considered. The solution for the temperature at any point in the fluid is found analytically. The isotherms and lines of constant flux are plotted.
