将稳定性理论应用于旋转喷嘴喷出的液体射流，分析了液体射流的破碎长度和液滴尺寸。通过将水、甲醇和甘油水溶液从转速为250-1450rpm的喷嘴中喷射出来，测量了破碎长度和液滴尺寸。随着液体速度的增加，出现了单液滴形成、层流和湍动射流。层流破碎长度随液体速度和旋转速度的增大而增大。层流射流形成的液滴直径随液体速度的增大而增大，随旋转速度的增大而减小。理论计算结果与实验数据吻合较好，与实验数据吻合较好。
Stability theory is applied to the liquid jet ejected from a rotating nozzle, and the breakup length and the drop size are analyzed. By the ejection of water, methanol and aqueous glycerol solution from a nozzle rotating at 250-1450 rpm, the breakup length and drop size were measured. As the liquid velocity increases, the single drop formation, laminar, and turbulent jet are observed. The laminar breakup length increases with the increase of the liquid velocity and the rotating velocity. The diameter of drops formed from the laminar jet increases with the increase of the liquid velocity and decreases with the increase of the rotating velocity. Predictions show a good agreement with experimental data of breakup length and drop size.
