【摘要】 以空心旋转射流的理论模型为基础［１］，通过实验对旋流喷嘴射流特性做进一步深入的研究，特别是实际射流形状的变化规律及喷嘴初始参数的变化规律．结果表明，旋流喷嘴的初始参数和空心射流内外表面压力差是决定射流形状的主要因素。更多还原

【Abstract】 Based on the theoretical model for the hollow swirling liquid jet at its initial stage, an experimental study and a further analysis have been conducted, especially on the variation of the shape of the hollow jet and its initial parameters. The results show that the initial parameters and the pressure deference between outer and inner surface of the hollow jet play a dominant role on the shape of the liquid jet.更多还原
