Abstract

The slope of an oval-trench dimple in the corridor package on the stabilized hydrodynamic section of the narrow channel has a dramatic effect on the anomalous intensification of the separated and vortex flows in the dimple, leading to a three- to fourfold decrease in the relative negative friction in the range of angles from 40° to 60°, an increase in the maximum velocity of separated and secondary flow up to 0.8 and 1.18 in relation to the average mass flow rate in the channel.

狭窄通道水力稳定段中单排椭圆形沟槽凹坑的倾角对分离湍流异常增强的影响

摘要

在狭窄通道的稳定水动力部分上，通道包中的椭圆形沟槽酒窝的斜率对酒窝中分离流和涡流的异常增强有显着影响，导致相对湿度降低三至四倍在40°到60°的角度范围内产生负摩擦，相对于通道中的平均质量流量，分离和二次流动的最大速度增加到0.8和1.18。
