Abstract In this paper, we present the results of experimental research into the influence of viscosity, surface and interfacial tension of the liquid on the position of transition boundaries between droplet interaction regimes and main characteristics (number and dimensions) of child droplets. We produce collision regime maps using the dimensionless linear interaction parameter, the Weber and Ohnesorge numbers. The key liquid characteristics are varied in the following ranges: dynamic viscosity 0.0014–0.0063 Pa·s; surface tension 0.0275–0.07269 N/m; interfacial tension 0.00341–0.04257 N/m. Water, glycerol, Diesel fuel, stabilizers, and emulsifiers are used to produce solutions and emulsions. The main findings describe how viscosity, surface tension, and interfacial tension affect the dimensions of child droplets together and separately. The findings obtained contribute to developing the chemical and petrochemical technologies based on collisions of the droplets of various compositions as well as the technologies of secondary atomization of droplets.

粘度、表面和界面张力对液滴碰撞的影响

摘要 在本文中，我们介绍了液体的粘度、表面和界面张力对液滴相互作用机制之间的过渡边界位置和子液滴的主要特征（数量和尺寸）的影响的实验研究结果。我们使用无量纲线性交互参数、Weber 和 Ohnesorge 数生成碰撞状态图。关键液体特性在以下范围内变化：动态粘度 0.0014–0.0063 Pa·s；表面张力 0.0275–0.07269 N/m；界面张力 0.00341–0.04257 N/m。水、甘油、柴油、稳定剂和乳化剂用于生产溶液和乳液。主要发现描述了粘度、表面张力和界面张力如何一起和单独影响子液滴的尺寸。
