Sloshing in Suspended Containers

Cooker, (Wave Motion, 0, 1994) reported original work on the
interactive dynamics between a fluid partially filling a single-compartment
container suspended as a bifilar pendulum to determine the frequency of small
amplitude motion of the system. Weidman (Bull. APS, 39, 1994)
extended the results of Cooker to include multi-compartment rectangular
containers, a cylindrical container, a 45 degree wedge container and a
hyperbolid container. We present the theoretical results for some of these
systems. Then fundamental mode frequency measurements will be presented for
fluids partially filling single- and multiple-compartment rectangular containers
and a cylindrical container. The results confirm the validity of the
shallow-water approach over a range of fluid/container mass ratios M and
pendulum lengths l varying from 0.5 m to 3.5 m.
Time permitting I will show preliminary measurements of
surface tension driven self-organization of particles floating on the surface of
water.
