【摘要】 介绍了溴化锂水溶液池沸腾换热的实验装置,以及溴化锂水溶液在真空条件下的池沸腾换热性能. 实验研究结果表明: 压力对池沸腾换热有一定影响,且随溶液浓度不同而有所不同; 浓度对池沸腾换热有明显影响,且随压力提高,影响增大; 管束对池沸腾换热有增强效应,水平管束的沸腾换热系数明显高于单管的沸腾换热系数.更多还原

【Abstract】 An experimental apparatus of the pool boiling heat transfer was developed and an experimental investigation on the pool boiling of water-lithium bromide solution has been conducted. The experimental results show that the pool boiling heat transfer is affected by pressure. The concentration of the solution has definite effect on pool boiling performance. For the horizontal tubes bundle an enhanced action on the pool boiling heat transfer exists. Heat transfer coefficient of the tube bundle is higher than that of a single tube.更多还原
