Eötvös Number
Eötvös number is proportional to { (gravitational force) / (surface tension force) } and is used in momentum transfer in general and atomization, and motion of bubbles and droplets calculations in particular. It is equivalent to (Bo). It is normally defined in the following form :
Where: |
| ||
L | = | Characteristic length |
|
rho | = | Density of bubble/droplet |
|
rho_f | = | Density of surrounding fluid | |
sigma | = | Surface tension |
