摘　　要：利用流体力学理论,对环孔雾化器喷出的气体射流运动进行了分析,着重研究了喷射顶角、喷射距离及节圆直径对射流流速的影响规律,导出了计算公式,得出了使射流保持较大流速的设计条件。By the theary of fluid mechanism , axial flow of gas exit jet has been analysed . The influences of jet apex angle and jet distance and knuckle round diameters on jet velocity have been analysed, the mathematical expression has been given out too. Design requirements of jet for producing maximum velocity have been also established.
