EFFECTS OF NON-DIMENSIONAL PARAMETERS ON THE MOTION OF THE HOLLOW SWIRLING LIQUID JET AT ITS INTITIAL STAGE

Keywords： swirl nozzle , initial stage , hollow swirling jet

本文以描述空心旋转射流初始阶段运动规律的理论模型[1]为依据，重点讨论了影响射流运动的无量纲参数：韦伯数，液膜内外压力差，液膜初始内外环半径比，初始旋流度，初始径向速度等。从而进一步加深了对旋流喷嘴所产生的空心旋转射流初始阶段运动及发展规律的认识。

Based on the theoretical model for the hollow swirling liquid jet at its initial stage, the results of a theoretical study on the effects of a number of non-dimensional parameters, including the Weber Number We, the pressure difference between the outer and inner surface of the hollow liquid jet dP, initial swirl number Γ0, initial ratio of outer and inner radii of the hollow jet and initial radial velocity NVr0, on the motion of the hollow liquid jet are reported.
