Abstract
Thermal energy storage (TES) is the central component of any renewable energy system (RES) and can considerably effect its overall efficiency. A good storage tank should enhance the stratification by restricting inlet mixing. In this paper, an experimental study is presented to evaluate the performance of domestic hot water storage tanks in discharging mode. Discharging of tank was conducted with different inlet flow rate to assess the effect of inlet mixing on thermal stratification. The study was conducted to visualize the combined results of temperature distribution, MIX number and Richardson number to predict the behavior of tank under dynamic mode. It was concluded that discharging rate of 800L/hour has the maximum mixing and thus the worst stratification for current scenario.
