the definition and calculation of fractional dimension are introduced briefly. fluctuating pressure signals from sediment? laden and aerated flow are processed by the reconstruction of phase space.
简要介绍分维的定义和计算方法,同时运用相空间重构法,对含沙掺气水流脉动压力信号进行处理,并计算浑水、清水、掺气三种不同水流状况的关联维数。
with the testing results of the cross-sectional mean velocity of aerated flow in spillway tunnel, the velocity of aerated flow in high speed flow is analyzed.
结果表明:在滩槽交界附近存在一个流速间断面,在这个区域水流所受阻力较大,过汇流口后,水槽内水流流态基本符合明渠流动特性。
in a special circulating system with high velocity flow, boundary shear stresses in clear water flow, aerated flow and sediment laden flow are measured.
在高速水流循环系统中,用自行研制的剪切力传感器分别量测了清水、掺气水流及挟沙水流壁面上的剪切力;
