真空状态下套装抑泡孔管的单管在溴化锂水溶液中的池沸腾换热

POOL BOILING HEAT TRANSFER ON A SINGLE TUBE JACKETED WITH PTRB IN LITHIUM BROMIDE WATER SOLUTION UNDER A VACUUM

本文报导了真空状态下套装不同尺寸的抑泡孔管的单管在溴化锂水溶液中的池沸腾传热实验研究结果,示出了压力(45-45cmmHg)、浓度(0-55wt％)、间隙尺寸(0.5-3.5mm)对沸腾换热的影响。由实验结果回归得到的准则方程可供真空状态下溴化锂水溶液中套装抑泡孔管的单管沸腾换热计算用。

This paper presents the experimental results of pool boiling heat transfer on a single tube jacketed with PTRB with various sizes in lithium bromide water solution under a vacuum and the effects of the pressure (from 45 to 450 mm Hg), the concentration (from o to 55 ωi%), and the gap size (from 0.5 to 3.5mm). A pool boiling heat transfer correlation equation is obtained by the ragressive method from the expsrimental data. It can be used for calculating the pool boiling heet transfer on a single tube jacketed with PTRB in lithium bromide water solution under a vacuum.
