摘　　要：液体在管内流动的效果对生产效率至关重要。本文主要讨论扰动元件类型及参数对扰动效果的影响。研究结果表明,当切深为螺杆设计的标准值时,湍流效果较好。对于标准螺杆型扰动元件,双头数标准螺杆型扰动元件效果最佳,单头数标准螺杆型扰动元件次之,三头数标准螺杆型扰动元件远差于其他两种。当圆管直径达到一定值后,直径越大,湍流效果越差。The effect of liquid flow in pipes has a crucial impact on production efficiency.The impact of disturbance element types and parameter variations on disturbance effects were discussed.The results indicated that when the cutting depth was the standard value for screw design,its turbulence effect was the best.For standard screw type disturbance elements,the double headed standard screw type disturbance element had the best effect,followed by the single headed and the three headed.When the diameter of the circular tube reached a certain value,the larger the diameter,the worse the turbulence effect.
