DETERMINATION AND ANALYSIS OF THE POTENTIALITIES OF THERMAL ENERGY STORAGE MATERIALS
Abstract
An extensive literature search was made to select as many potential heat storage materials as possi le. A number of chemical compounds, binary alloys, and double salts were found which had melting points in the range of interest. Magnesium silicide, calcium silicide and lithium metaborate, were recommended for early testing on the basis of their relatively low melting points and probable compatibility with container materials. An experimental program to measure various physical properties of candidate materials was initiated. The latent heat of fusion, enthalpy, melting point, liquid density, viscosity, coefficient of expansion, and thermal conductivity of the candidate heat storage materials were measured. Three storage system configurations were analyzed: (1) storage material in cylindrical capsules, (2) storage material in the annulus between concentric cylinders, and (3) storage material in thin blocks whose shape conforms to the shape of the working fluid reservoir.
