Laplace number



The Laplace number (La), also known as the Suratman number (Su), is a dimensionless number used in the characterization of free surface fluid dynamics. It is represents a ratio of surface tension to the momentum-transport (especially dissipation) inside a fluid.

It is defined as follows:

La = Su = \frac{\sigma \rho L}{\mu^2}\,

where:
