BAFFLE EFFECT OF SLOSHING INDUCEDFLOWS IN RESPONSE TO AXIAL IMPULSE IN MICROGRAVITY

摘要

Sloshing dynamics for partially filled liquid of superfluid helium Ⅱ in a rotating dewar container in resPonse to axial impulse is investigated. The study includes howrotating bubble of suPerfluid he1ium Ⅱ reacts to the impulse in microgravity, how ampli-tudes of bubble mass center fluctuate with growth and decay of disturbances, how thesedisturbances in fluid system feed back to dewar in terms of force and moment through thedynamics of sloshing waves, and hwo the differences react on the container with andwithout the baffle.
