【摘要】 根据水流中滞点压力与流速平方成正比的关系,本文介绍用硅压阻压力传感器检测滞点流速水头,由计算机进行实时数据采集的浑水脉动流速量测系统的原理及量测成果。通过对清水及推移质换沙水流、悬移质挟沙水流的量测证明,所测清水紊动强度的分布与激光流速仪量测结果一致。并能成功地用于挟沙水流流速的测量。更多还原

【Abstract】 The fluctuation velocity of sediment-Iaden flows in open channal are measured using the velocimetrymade by oneself in this study, Velocityes are measured by use of fofal pressure probe based on Pitter tubeprinciple. The experiments show that measuring result of this Volocimetry is similar to the results meas-ured using laser-Doppler Velocimetry, So it can be used for Sediment-laden flow.更多还原
