Investigation on Liquid Breakup Regimes and Atomization Performance of Slinger
文献摘要：
A theoretical and experimental investigation on the liquid breakup regimes of slinger is presented in this paper. The theoretical results show that in the round orifice of the slinger, if the contact angle between the liquid and the wall is less than 90° , the liquid surface tension will inhibit the liquid lateral flowing under the Coriolis force. The formula used to predict the liquid regime leaving the orifice in the past was proved to be inaccurate, which is explained by two assumptions presented in this paper. The breakup regimes of the liquid film are related to the Weber number, and the characteristic length of the Weber number is equivalent to the thickness of the liquid film. The liquid film performed subcritical breakup when the Weber number was small and performed supercritical breakup when the Weber number was large. But when the Weber number was in the middle state, the breakup regimes could not be determined. The liquid breakup regimes affected the primary breakup of the liquid, but a lot of tiny droplets were produced in the secondary breakup, which led to poor correlation between the spray Sauter Mean Diameter ( SMD) and the Weber number corresponding to various liquid breakup regimes. On the whole, the spray SMD performs a power relationship with the Weber number corresponding to the liquid film regime, and the correlation coefficient is close to 0.9.
