Laplace number
From Wikipedia, the free encyclopedia
(Redirected from Suratman 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:
- <math>La = Su = \frac{\sigma \rho L}{\mu^2}\,</math>
where:
- σ = surface tension
- ρ = density
- L = characteristic length
- μ = dynamic viscosity
[edit] See also
- Ohnesorge number - There is an inverse relationship, <math>La = Oh^{-2}</math>, between the Laplace number and the Ohnesorge number.
