摘　　要：为了研究非自由淹没多股射流流场的运动规律 ,了解非自由射流固壁及射流方式对流场结构的影响 ,利用计算机模拟了三维多股射流的几种情况 ,通过分析 。In order to know the flow field of multi stream emerged jetting from rotating drill bits and find out the effect of solid walls in limited jetting space on flow field construction, several cases of three dimensioned multi stream jetting are simulated by computer. The forming process of flow and related rules of fluid motion are showed on the beasis of simulation results.
