EXPERIMENTAL ANALYSIS OF PARTIAL AND FULLY CHARGED THERMAL STRATIFIED HOT WATER STORAGE TANKS

Developing competent and economical energy storage devices such as thermal energy storage have great importance as it reduces the gap between demand and supply of energy Presently, the most common storage devices utilize phase change materials (commonly known as eutectic salts), rock beds and hot water storage. In most cases stratified storage tanks with various capacities are employed for storing energy which was most economical. Some analytical simulations and experimental investigations of the effect of thermal stratification in storage systems were carried out by a number of investigators who showed that strati fication improves the performance of solar systems. By considering the phenomenon of mixing an d other degradation mechanisms will provide an higher limit to the performance of a stratified thermocline hot water storage tank as they influenced a lot and provides closure picture to the practical situation.
