Heat Extraction from Porous Media Using a Vertical Type Heat Exchanger.

Abstract

Heat extraction rate from porous media saturated with water using a vertical type heat exchanger has been studied experimentally and analyzed numerically. The unsteady heat extraction characteristics are presented, and the effect of the flow rate of the heat extraction medium of water in a heat exchanger and that of the Rayleigh number on heat extraction rate are discussed. The present computed results predict comparatively well the heat extraction rate from porous media saturated with water in the range of the parameters covered.
