The research result demonstrates that along with the increment of reynolds number , the root mean square value of outer fluctuating magnitude of the external diameter in fall frequency band increases , the root mean square value of fluctuating magnitude of the external diameter in high frequency band decreses , demonstrating that the fluctuation of flexible pipe wall changes fluctuation don field of original rigid pipe , large - size eddy motion increases and small - size eddy motion decreases , this reduces energy loss and increases friction reduction effectiveness
研究结果表明：随着雷诺数的增加，全频带的外径脉动的均方根值加大，但高频带外径脉动的均方根值减小，说明柔性管管壁脉动确实改变了原刚性管的脉动流场，大尺度涡的运动加剧，低尺度涡运动减弱，从而使得能量损失减少，减阻效果增大。
