  1. 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

    研究結果表明:隨著雷諾數的增加,全頻帶的外徑脈動的均方根值加大,但高頻帶外徑脈動的均方根值減小,說明柔性管管壁脈動確實改變了原剛性管的脈動流場,大尺度渦的運動加劇,低尺度渦運動減弱,從而使得能量損失減少,減阻效果增大。
