... transfer in the channel is higher than that estimated for the cylindrical annulus. Regarding optimal design selection, the entropy generation analysis, detailed in this paper, suggests a preference for the cylindrical annulus geometry. Our results may guide designers to select from the studied...

...Rosemarie Mohais; Chaoshui Xu; Peter Dowd We present an analysis of fluid flow and heat transfer through a single horizontal channel with permeable walls which are at different temperatures. The problem is set in the context of hot dry rock geothermal energy extraction where water, introduced...

...D. A. Nield; A. V. Kuznetsov An analytic solution is obtained for the problem of fully developed forced convection in a channel between parallel plane walls, partly occupied by a bidisperse porous medium (BDPM) and partly by a fluid clear of solid material, the distribution of material being...

...A. V. Kuznetsov; D. A. Nield Flow in a three-layer channel is modeled analytically. The channel consists of a transition layer sandwiched between a porous medium and a fluid clear of solid material. Within the transition layer, the reciprocal of the permeability varies linearly across the channel...

... parallel plates without a chim- ney has been widely studied. The data of Elenbaas (1942) provide the foundation for heat transfer from a single isothermal channel without chimney enhancement. For flows without chimneys, the parallel-plate analysis described by Fisher et al. (1997) reduces to the analysis...
