Ursell Number Calculator
Posted by Dinesh onOnline Ursell formula calculator to calculate ursell number for estimate nonlinearity of long surface gravity waves on a fluid layer.
The Ursell number indicates the nonlinearity of long surface gravity waves on a fluid layer. This dimensionless parameter is named after Fritz Ursell, who discussed its significance in 1953.
Ursell Number Calculation
Formula:
where,
| H is the wave height (the difference between the elevations of the wave crest and trough). |
| λ is the wavelength, which has to be large compared to the depth, λ ≫ h. |
| h is the mean water depth. |
| U is the Ursell Number |
