游泳水槽的气泡运动规律及去除方法研究

Motion and removing of the air bubble in swimming flume

游泳水槽作为一个先进的工具,可有效地提高竞技游泳水平。目前游泳水槽建造技术尤其是对水流的控制技术已趋于成熟,但水槽内的气泡将会影响对运动员技术动作观测和图象解析,并对运动员游泳姿态测试、分析和改进带来困难。本文通过对游泳水槽结构及水槽中水流流动状况分析得到了气泡产生的主要原因,并研究了气泡运动的规律,提出了减少气泡产生的合理方法以及去除气泡的合理设计,为现有的游泳水槽改进提供良好方案,为今后自主设计先进的游泳训练用水槽提供技术支撑。

As an advanced and mature tool, the swimming flume can be used to enhance the research and training ability effectively in the field of competitive swimming. The air bubbles appearing in the flume influence the observation on athlete＇s movement but are difficult to be removed or deduced. The authors investigated the flowing characteristics in the flume and present in this paper the relationship between the air bubbles appearing and the configuration of the flume. On the basis of the motion analyses of air bubbles, some proposals to flume design for deducing the air bubbles in the flume are presented and can be helpful to the future design.
