Response of lateral impulse on liquid helium sloshing with baffle effect in microgravity

Sloshing dynamics within a partially filled rotating dewar of superfluid helium II are investigated in response to lateral impulse. The study, including how the rotating bubble of superfluid helium II reacts to the impulse in microgravity, how amplitudes of bubble mass center fluctuate with growth a...

Description
Summary:Sloshing dynamics within a partially filled rotating dewar of superfluid helium II are investigated in response to lateral impulse. The study, including how the rotating bubble of superfluid helium II reacts to the impulse in microgravity, how amplitudes of bubble mass center fluctuate with growth and decay of disturbances, how slosh reaction forces amplify and decay in response to lateral impulse, and how sloshing dynamics differ with and without a baffle, are investigated. The numerical computation of sloshing dynamics is based on the non-inertial frame dewar bound coordinate. Results of the studies are illustrated.
