Performance Evaluation of Stratified TES using Sigmoid Dose Response Function

Temperature distribution on the operating stratified thermal energy storage (TES) is commonly available as discrete data. Due to this, it is difficult to conduct performance evaluation based on thermocline profile, because limit points could not be determined accurately. This paper discusses a pract...
