具有环状截面的脉冲萃取柱可以有效地提供更大的柱截面积,并且保证核燃料的临界安全。本文研究了环形脉冲萃取柱中两相流动特性。实验柱由内径为50mm玻璃管构成,中间插入外径为16mm或30mm的不锈钢内管。实验中所测得的数据用半经验公式进行了关联。环形柱的液泛数据与具有相同截面积的一般园柱形萃取柱的液泛数据进行了比较。
Pulsed extraction columns with a circular cross-section can effectively provide larger column cross-sections and ensure the critical safety of nuclear fuel. In this paper, the characteristics of two-phase flow in a ring-shaped pulse column are studied. The experimental column is composed of a glass tube with an inner diameter of 50 mm and a stainless steel inner tube with an outer diameter of 16 mm or 30 mm. The data measured in the experiment were correlated using a semi-empirical formula. Fluvial data for ring columns were compared to pan data for a typical cylindrical column with the same cross-sectional area.
