Capillary Number
Capillary number is proportional to { (viscous force) / (surface tension force) } and is used in momentum transfer in general and atomization and 2-phase flow in beds of solids calculations in particular. It is equivalent to (We/Re). It is normally defined in the following form
Where: | ||
gc | = | Dimensional constant |
mu | = | Viscosity |
sigma | = | Surface tension |
V | = | Velocity |
