| Abstract: | In this paper,the software of Fluent 6.2.16 was used to establish the model of phase change thermal storage equipment with novel flat heat pipe,and the melt process was simulated taking paraffin wax as the phase change material.Based on the simulation,the variation trends of temperature field,liquid volume fraction and interface of phase change were discussed.Furthermore,the heat transfer process was compared under different size of fins and different temperature differences,hence the influence rules of the... |
