摘要
针对常规除湿溶液——LiCl溶液的池内核态沸腾特性展开实验研究。研究发现:实验范围内,LiCl溶液的沸腾温度随着浓度的增加而升高;LiCl溶液的沸腾换热系数远低于纯水,并随浓度的增加而降低。沸腾换热过程受工质诸多物性参数的共同影响,溶液沸腾换热机理较单一组分液体沸腾更为复杂,有待进一步深入研究。
The pool nucleate boiling characteristics of the aqueous LiC1 solution is experimentally studied, and the results show. the boiling temperature of the aqueous LiC1 solution increases with the concentration going up,the heat transfer coefficient is lower than that of water and decrease with the concentration going down. The boiling heat transfer process is affected by many physical parameters of the working fluid, and the boiling heat transfer mechanism is more complicated. So more study on the subject is needed.
