Resumo

Recent interest in the possibility of using power plant cooling water in a buried-pipe network to warm soil for agriculture has given impetus to the study of simultaneous heat and mass transfer in soil. The feasibility of soil warming rests to a large extent upon understanding and controlling the energy and mass transports in the soil surrounding the pipes. This paper focuses on the derivation of the governing equations for heat and mass transfer, on the constitutive relationships describing the transport processes in the porous medium, and on the determination of accurate values for the associated transport coefficients for soil. A brief summary is also presented of the simulation of a soil warming system based upon the transport equations developed as well as a review of key conclusions regarding the feasibility of soil warming for agriculture.
