摘要
以 90～ 15 0 μm的标准细沙为研究对象 ,进行垂直入水群沙射流的实验研究 ,给出群沙入水后的运动规律。
In this paper,the motion of sand jets into stagnant water is experimentally investigated The size of the sand is 90-150um Using a digital video camera,the Patterns of the sand cloud after discharge were obtained In reclamations,the first problem to be solved is to obtain the dynamic behavior of the sand cloud after discharge
