Ohnesorge Number
Ohnesorge number is proportional to { (viscous force) / (sqrt (inertial force . surface tension force)) } and is used in momentum transfer in general and atomization calculations in particular. It is equivalent to (SQRT(We) / Re). It is normally defined in the following form :
Where: | ||
gc | = | Dimensional constant |
L | = | Characteristic length |
mu | = | Viscosity |
rho | = | Density |
sigma | = | Surface tension |
