چکیده
For the intermittence and instability of solar energy, energy storage can be a good solution in many civil industrial thermal scenarios. With advantages low cost, simple structure, high efficiency, single-tank system is competitive way (TES). In this study, two-dimensional flow heat transfer model cylindrical tank with water as fluid (HTF) developed, which effects time, velocity, height-to-diameter ratio on thermocline thickness have been highlighted. The results show that increasing during charging discharging processes, it increases increase inlet velocity height to diameter ratio. It emphasized our cases when time period t 14,400 s, uin 4.577 × 10−4 m/s, H/D 1.2, performance evaluation index reaches maximum 0.9575, efficiency highest. expected all findings herein provide fundamental understanding design operation heating for applications.

Up to day, 70% of the gross electricity (~ 20000 TWh) is produced via fossil fuel; to reduce this share and abate CO2 emissions the energy system will face a dramatic change in the near future consisting in a significant introduction of intermittent renewable energy sources. The implementation of this step change will be possible only through efficient and economic grid-scale electrical energy ...
