Model Validation and Stacking Optimization Based on Packed Bed Phase Change Thermal Storage

Blog Article

A two-dimensional unsteady continuous solid phase model was established for the packed bed phase change thermal storage tank, and its thermal storage performance was numerically studied.The simulation results reveal the change of thermocline and the distribution state of heat transfer temperature difference during thermal storage.The influence of the initial temperatures, inlet temperatures and phase change capsule diameters on the thermal storage performance here were investigated, the results were compared with the existing literature for verification.In order to further improve the packing rate, this paper puts forward the packing optimization scheme of particle diameter obeying Alfred distribution in combination with the theory of particle accumulation.

According to the calculation results, this optimization method significantly improves iphone 14 price san francisco thermal storage under the condition of a small increase in thermal storage time, and has a good optimization effect.
