Transient Heat Release Characteristics of a Latent Heat Storage Vessel Packed with Polyethylene Pellets

摘要

Transient heat release characteristics of a latent heat storage vessel packed with surface cross- linked form-stabilized high-density polyethylene pellets as a phase change material (PCM) have been investigated numerically and experimentally. The obtained results revealed the effects of the inlet velocity, the inlet temperature of ethylene glycol/water solution as a heat transfer medium, and the amount of the PCM on the heat release characteristics. As a result, the nondimensional correla- tion equation of the completion time of the heat release process was derived as a function of some nondimensional parameters.
