【摘要】 动态冰浆由于具有较强的蓄能和传热能力,日益受到人们的重视。文中建立了动态冰浆传热特性的数理模型,并利用已知的载流溶液和冰晶的物性参数,得到了动态冰浆在水平直管、等热流加热条件下的传热系数,根据计算结果,分析了传热系数随着冰浆浓度的变化的规律和冰浆流速和管径对动态冰浆传热性能的影响。更多还原

【Abstract】 Investigations on characteristics of ice slurry become popular due to its superior thermal energy storage and heat transfer performance.This paper constructs a physical and mathematic heat transfer model of ice slurry,using physical property parameters of carrier fluid and ice particles to calculate the heat transfer coefficients of ice slurries flown in horizontal pipes under constant heat flux.The effect of ice concentration,ice slurry velocity and pipe diameter on heat transfer coefficient are discussed based on analysis results.更多还原
