| 摘 要： | 应用质量守恒定律和动量守恒定律，建立了描述旋流喷嘴射流初始阶段运动规律的非线性常微分方程组，该方程组可以用数值方法方便地求解，理论计算结果与实验拍摄到的射流照片吻合很好，说明空心旋转射流受扰动失稳破碎成液滴管的最基本运动状态，是进一步从理论上研究该射液破碎雾化机理的基础。

| Abstract: | The motion of the liquid jet from a swirl nozzle at its initial stage has been studied theoretically.A set of non linear differential equations describing the motion of the jet is obtained using the equations of conservation of mass and conservation of momentum.The equations can be conveniently solved by the numerical method.An experimental study on the hollow swirling liquid jet has also been conducted.The experimental result agrees well with that of the theoretical analysis.The results can be considered as the basic jet flow pattern from a swirl nozzle before the breakup of the swirling liquid jet due to its instability,and may be regarded as a basis for further study of this problem. |
