摘要	Liquid flowing on a curved solid surface usually leads to a typical teapot effect. As the jet velocity increases, the liquid detaches from a curved solid surface completely in one streamline or partially in multiple streamlines. We called the latter splashing. Former studies attributed the splashing behavior to the breaking of the balance between the centrifugal force and the pressure drop across the liquid flow. This study disclosed that the parameters of surface tension, viscosity, and additive molecules of liquid significantly affected the jet splashing in teapot effect. A liquid with a higher Weber number (lower surface tension) and a lower Reynolds number (higher viscosity) prefers to separate from the solid surface in one streamline. Besides, a liquid with larger molecular weight additives is easier to splash. Molecular dynamics simulations disclosed that a higher water molecule density around the additive molecules with a larger cohesive force could more effectively suppress splashing. There is no splashing when the cohesive force is larger than the capillary adhesion force. Otherwise, splashing would occur. This study discloses the importance of cohesive force in the splashing in teapot effect, which might provide an effective guide for industrial applications by tuning the splashing.
