Sloshing can occur in swimming pools, trucks carrying liquids, rocket vehicle propellant tanks and in other situations.
Sloshing of propellants may adversely affect the stability of a space vehicle and the integrity of the tank structure. Sloshing describes the free-surface oscillations of fluid in a partially filled tank. The oscillations result from lateral and longitudinal displacements or angular motions of the vehicle.
I have added a function for calculating slosh natural frequencies to the Vibrationdata GUI package.
Matlab script: Vibrationdata Signal Analysis Package
The slosh function may be accessed via:
