Heat Transfer Through a Porous Medium,Here we also assume that heat conduction in the solid and fluid phases takes place in parallel so that there is no net heat transfer from one phase to the other. More complex situations will be considered in Sect. .. The fundamentals of heat transfer in porous media also are presented in Bejan et al. (2004) and Bejan (2004a).

In the simplest situation (single-phase flow) the void is saturated by a single fluid. In “two-phase flow” a liquid and a gas share the void space.

Very shortly we shall assume that there is local thermal equilibrium so that ..?=?..?=?., where .. and .. are the temperatures of the solid and fluid phases, respectively.

In this chapter we analyze the basic heat transfer question by looking only at . situations, in which the fluid flow is caused (forced) by an external

At large values of Ra thermal boundary layers are formed, and boundary layer theory is the obvious method of investigation. This approach forms the subject of much of this chapter. We follow to a large extent t

In this chapter, we turn our attention to situations in which a change of phase occurs, for example, melting or evaporation upon heating and solidification or condensation upon cooling. These convection problems constitute a relatively new and activ
