Analysis on Heat Release Characteristics of Molten Salt-based Latent Heat Thermal Energy Storage Device
摘要
Abstract
In order to provide more critical insights for the design and operational strategy of latent heat storage en-ergy utilization systems based on molten salt,the heat release process of a phase change storage unit utilizing binary eutectic nitrates(NaNO3 and KNO3,mass ratio of 23∶27)was investigated through numerical analysis in this study.The solidification and heat release processes in the phase change storage unit,with air serving as the heat transfer fluid,were simulated and calculated.Subsequently,the dynamic evolution characteristics of temperature and liquid phase fraction within the molten salt,the heat release rate of the phase change storage unit,and the outlet tempera-ture of the air were analyzed and evaluated.The findings revealed that natural convection within the molten salt continued to play a significant role during the heat release process.As the phase transition progressed,the liquid phase fraction of the molten salt generally demonstrated a parabolic trend.Concurrently,both the heat release rate and the air outlet temperature exhibited linear decreases.关键词
