Abstract
Convective heat transfer in fluid-saturated porous media has received much attention in recent years because of its important applications both in technology and geothermal energy recovery. Detailed reviews of the subject, including exhaustive lists of references, were recently performed by Ingham and Pop [17,18], Nield and Bejan [32], Vafai [40], and Pop and Ingham [33]. Most of the recent research on convective flow in porous media has been directed on the problems of steady free and mixed convection flows over heated bodies embedded in fluid-saturated porous media. However, unsteady convective boundary-layer flow problems have not, so far, received as much attention. Perhaps, the first study on unsteady boundary-layer flow on flat surfaces in porous media was made by Johnson and Cheng [19] who found similarity solutions for certain variations of the wall temperature distributions. The more common cases, in general, involve transient convection, which is non-similar and hence more complicated mathematically. The interested reader can find an excellent collection of papers on unsteady convective flow problems over heated bodies embedded in a fluid-saturated porous medium in the review papers by Bradean et al. [2] and Pop et al. [34], and in the book by Pop and Ingham [33].
