weber number

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 interface curvature is large in multi-phase flow.

the weber number represents the ratio of inertial force to surface tension effect. the smaller the weber number, the more important surface tension is, such as capillarity, soap bubbles, surface tension and other small-scale problems such as tension waves. generally speaking, for large-scale problems, the weber number is much greater than 1.0 and the role of surface tension is negligible.
