Identifying the regime of a liquid jet is necessary to determine the physical mechanisms causing breakup and consequently how to model the jet. Existing regime diagrams are based on a small amount of data classified by superficial visual characteristics, making these diagrams too inaccurate to reliably determine the correct regime. A more accurate regime diagram is developed using primarily a large compilation of breakup length data combined with theory where the data is sparse. Improvements in the regime diagram include a new regime, the addition of two critical Reynolds numbers and the turbulence intensity as variables, and the recognition that how the regimes change with increasing velocity (i.e., Rayleigh to first wind-induced to second wind-induced to atomization) is not universal.

重新评估射流破碎状态图

确定液体射流的状态对于确定导致破裂的物理机制以及因此如何对射流进行建模十分必要。现有的状态图是基于通过表面视觉特征分类的少量数据的，这使得这些图过于不准确，无法可靠地确定正确的状态。首先主要使用大量的解体长度数据和稀疏理论相结合来开发更精确的状态图。方案图的改进包括新方案，增加两个临界雷诺数和湍流强度作为变量，以及认识到方案如何随速度增加而变化（即，瑞利（Rayleigh）从第一风诱发到第二风诱发至雾化）不是通用的。
