摘要: 报道对两种国产高聚物添加剂的极稀水溶液在较高流速下核沸腾传热的实验研究结果,包括强化效果及其持久性.

Abstract: A special open-circuit experimental system was set-up with which the sub-cooled nucleate flow boiling experiments could be carried out in a quite wide range of working conditions and the mechanical degradation of polymers could be much reduced. Very dilute aqueous solutions ot polymeric additives (HEC, PAM) were experimented with higher heat flux (1×105-1.5×106W/m2) and flowing velocity (0.3-1.2m/s). The results were summarized and discussed.
