A STUDY ON PHASE CHANGES OF HETEROGENEOUS COMPOSITE MATERIALS.

Author(s) : HIRASAWA Y.

Type of article: Article

Summary

THE STUDY IS A BASIC INVESTIGATION OF THE PHASE CHANGE PROBLEM OF A THERMAL ENERGY STORAGE MATERIAL CONSISTING OF A PHASE-CHANGE MATERIAL AND CONDUCTIVE SOLIDS TO PROMOTE THE HEAT TRANSFER RATE. EXPERIMENTS WERE CARRIED OUT, USING WATER CONTAINING COILED COPPER WIRES. IT WAS FOUND THAT THE PHASE-CHANGE RATE OF THE THERMAL ENERGY STORAGE MATERIAL WAS INCREASED CONSIDERABLY BY THE ADDITION OF THE WIRES DESPITE THE SMALL EFFECTS OF THE VOLUME RATIO AND THE ARRANGEMENT. THE NUMERICAL CALCULATION WAS PERFORMED TO SIMULATE THE PHASE-CHANGE PROCESS. THE CALCULATED RESULTS AGREED WELL WITH THE EXPERIMENTAL RESULTS.
