Research of heat transfer characteristics in the real element of high temperature thermal energy storage
Abstract
In this investigation of a high-temperature thermal energy storage system, a round tube with an inside diameter of 10 mm and a wall thickness of 1 mm was chosen as the experimental channel. The tube was made of stainless steel and bent into a V-shape. Fifty-eight capsules with LiF as the PCM were installed outside the channel. Heat input and PCM fusion were realized as a result of current flow throught the tube wall, with thermal energy added from a resistance heater installed around the capsules. A special device assures a constant flow rate and inlet temperature of the working gas. Data on the efficiency of the PCM are presented and analyzed.
