摘要
采用Ｎａｖｉｅｒ－ｓｔｏｋｅｓ流体力学方程描述喷咀内部旋动流体和喷咀外部旋转射流的流动状态。在微小单元段速度作某些假定的条件下，求得速度和压力的分析解；研究旋转液体射流的雾化理论，讨论影响雾化的主要因素，并通过实验方法观察雾化状态和测量雾化角；最后给出实例。
The paper presents flow states of the swirl fluid inside the sprayer and swirl-liquid jet outsLide the sprayer with Navier-stokes hydromechanics equations.Usingsome hypothetic condition for velocities in the small element bodies,the analyticalsolutions of the velocities and pressure have been obtained.The atomisation theory ofthe swirl-liquid jet is studied and influence spraying main factors are discussed.Weobserue spraying states and measure atomisation angle by an experimental method. Examples are also given.
