Experimental study on the turbulence flux in sediment-laden flow

  • 摘要: 利用MicroADV的声强衰减与泥沙浓度的关系,提供一种无接触测量含沙量浓度的方法;同时根据连续采样得到脉动的泥沙浓度,对这种脉动浓度进行了初步分析并根据得到脉动浓度,初步定量地研究了紊动扩散通量大小及其平衡关系.

     

    Abstract: The laboratory calibration were used to determine the relationship between backscattered signal strength and sediment concentration.A non-intrusively way of concentration measurement was introduced, and the inner fluctuation of concentration was analyzed rudimentarily.Finally,according to the fluctuation concentration acquired by MicroADV,the equilibrium of upward flux and downward flux were compared quantificationaly.
