Abstract: 本文以 90~ 1 5 0 μm的标准细沙为研究对象 ,利用超声波速度剖面测量仪和数码摄录机进行了垂直入水群沙射流的实验研究 ,给出了的群沙入水后的运动规律 .我们发现 ,群沙湍射入水的一霎那 ,底部瞬时产生反射波 ,由它带动的流速与群沙入水带动的流速同量级
In this paper, the motion of sand jets acting into stagnant water is experimentally investigated. The size of the sand used is 90~150μm. By using a digital video camera and Ultrasonic Velocity Profile (UVP) measurement, the patterns of the sand cloud after discharge are obtained. The reflective wave from the bottom can also be observed by using UVP transducer.
