Weber number
The Weber number is a dimensionless number in fluid mechanics. It is used to analyze fluid motion when there is an interface between different fluids, especially when the curvature of the interface is large in multiphase flow.
The Weber number represents the ratio of the inertial force to the surface tension effect, and the smaller the Weber number, the more important the surface tension is, such as small-scale problems such as capillary phenomena, soap bubbles, and surface tension waves. Generally speaking, for large-scale problems, the Weber number is much greater than 1.0, and the role of surface tension can be ignored.
