Abstract

Abstract: After using the measured data to validate numerical models, the flow field analysis software Fluent was adopted to build a three-dimensional mathematical model, for calculating the chamber flow field in the process of filling water, and analyzing evolution of vertical flow field in the filling process. The study shows that when scale space is certain and each hole jets uniformly, if the number of collateral hole increases, the number of swirl also increases, but the swirl range is reduced, which is in favor of the hull moored.

摘要： 采用流场计算分析软件Fluent，在利用实测数据对数值模型进行验证后，建立三维数学模型模拟计算了船闸闸墙长廊道输水系统充水过程中的闸室流场，并对输水过程中闸室流场垂向演变规律进行了分析。研究表明：在尺度空间一定和各孔射流比较均匀的条件下，增加侧支孔的数量，漩涡数量增加，漩涡范围减小，有利于船体停泊。
