As we consider simultaneous fluid flow and heat transfer in porous media, the role of the macroscopic (Darcean) and microscopic (pore-level) velocity fields on the temperature field needs to be examined.

Solar Convection and Magneto-Convection
1996We explore the general properties of convection in a solar surface layer. Our three-dimensional simulations use a tabulated equation of state that includes excitation and ionization of hydrogen and other abundant atoms, and the formation of H2 molecules. The radiative energy exchange is determined by solving the radiative transfer equation.

Convective Plumes in a Convective Field
Journal of the Atmospheric Sciences, 1970Abstract 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 ...

Rotation, convection, and magnetic activity in lower main-sequence stars
, 1984Rotation periods are reported for 14 main-sequence stars, bringing the total number of such stars with well-determined rotation periods to 41. It is found that the mean level of their Ca n H and K emission (averaged over 15 years) is correlated with ...

Conduction and Convection [PDF]
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.
