Heat transfer enhancement of ice storage capsules for the storage of grain in low temperature
Encapsulated ice storage is an efficient cooling energy storage technology that is beneficial for peak-load shifting of the power grid and can achieve efficient grain storage in low temperature with reduced energy consumption.This paper conducts a numerical simulation study on the ice storage capsules configured with branching pin fins based on the enthalpy-porosity method.The typical solidification process is analyzed to clarify the necessity of fins for ice storage capsules.Furthermore,the impact of the fin length ratio a on the temperature response,fully so-lidification time and cooling energy storage capacity is discussed,thereby providing a clear direc-tion for the design of encapsulated ice storage devices.
