组合式循环水槽的设计及其特点

作者研制的组合循环水槽不但保留了已被广泛使用的直水槽及环形水槽的某些优点,而且弥补了它们的不足之处,例如,在直水槽中不能产生稳定循环水流,在环形水槽中存在横向环流等.因此,它可以作为研究水流及泥沙运动特性的一种较为有效的实验设备。 本文阐述了该水槽的设计思想及结构特点,并从理论上及实验上对它进行分析.

The Design of Combined Circular Channel and Its Characteristics

The combined circular channel which has been developed by the author not only retains some advantages of the widely-used straight channel and circular channel; but also remedies some of their defects, such as the steady circulating flow which cannot be generated in straight channel can be genera-ted in the combined circular channel and the traverse circulating flow which cannot be eliminated in the circular channel can be eliminated in the combined circular channel. So it can be used as a more effective laboratory equipment in the research of flow and sediment movement.This paper deals with the design idea and the structural feature of this kind of channel and it also explores for improving the experimental con-dition of circulating flow in theory and experiment.
