RESEARCH DIRECTED TOWARD THE STUDY OF HEAT TRANSFER IN COMPLEX ROCK SYSTEMS.
Abstract
This study is part of a program conducted by the Air Force Cambridge Research Laboratories on methods of detection and utilization of lunar water resources. The two principal objectives of this study were: 1. To aid in the assessment of lunar water extraction processes by obtaining data on the physical, thermal and mechanical properties of hydrated minerals and rock systems, and 2. To analyze the heat and mass transfer associated with several possible lunar water extraction processes, using data obtained from literature and from experimental studies. Particular emphasis was to be placed on heat transfer and control in fractured and unfractured rock systems containing hydrated minerals. Literature data on the density, thermal conductivity, specific heat, permeability, porosity, thermal diffusivity, and moisture content of rock systems are assembled and tabulated. Experimental data for six typical rocks were obtained and compared to literature data. The apparatus and methods used in the experimental program are described. The results of calculations of the heat and mass transfer associated with extraction of water from subsurface deposits and mined deposits are presented. (Author)
