Effect of latent heat on frost penetration in moist soil

Description: Substantial differences have been found between measured and computed heat losses from a large in-ground thermal storage tank used for annual cycle heat storage. One suspected source of error in the computation was the neglect of the latent heat effects in the moist soil and efforts have been made to examine these. One of these effects, that was due to freezing and thawing of the soil moisture is discussed, and the results of some simulations of the effect in a numerical model are presented.

Experimental Study of the Storage of Thermal Energy in Confined Aquifers. Final Report, July 1, 1977-December 31, 1979

Description: To aid in testing the idea of storing thermal energy in aquifers, a two cycle experiment was performed by Auburn University in which heated water was stored in a confined aquifer and then recovered. During the first cycle, 54,784 m/sup 3/ of water were pumped from a shallow supply aquifer, heated to an average temperature of 55/sup 0/C, and injected into a deeper confined aquifer where the ambient temperature was 20/sup 0/C. After a storage period of 51 days, 55,345 m/sup 3/ of water were produ… more

Design, Performance, and Analysis of an Aquifer Thermal-Energy-Storage Experiment Using the Doublet-Well Configuration

Description: In March 1980 Auburn University began series of aquifer thermal energy storage (ATES) experiments using the doublet well configuration. The test site was in Mobile, Alabama. The objectives of the three experimental cycles were to demonstrate the technical feasibility of the ATES concept, to identify and resolve operational problems, and to acquire a data base for developing and testing mathematical models. Pre-injection tests were performed and analyses of hydraulic, geochemical, and thermodyna… more

Thermal energy storage market-oriented background paper

Description: Thermal energy storage (TES) technologies and their applications are discussed. The markets and commercialization status and potential are explored. ERDA TES program plans are presented. It is concluded that the only TES systems ready for immediate commercialization are storage water heating and space heating charged with off-peak electricity. All that is needed for commercialization to occur is the introduction of appropriate split electricity rates or load management contracts. In the near-te… more

Initial study of thermal energy storage in unconfined aquifers. [UCATES]

Description: Convective heat transport in unconfined aquifers is modeled in a semi-analytic way. The transient groundwater flow is modeled by superposition of analytic functions, whereby changes in the aquifer storage are represented by a network of triangles, each with a linearly varying sink distribution. This analytic formulation incorporates the nonlinearity of the differential equation for unconfined flow and eliminates numerical dispersion in modeling heat convection. The thermal losses through the aq… more
