M. Larson et al., SIMULATIONS OF THE BEHAVIOR OF HELIUM IN A THERMAL-CONDUCTIVITY CELL, Journal of low temperature physics, 113(3-4), 1998, pp. 561-566
We have performed numerical simulations of the behavior in a one-dimen
sional thermal conductivity cell of helium, as it is ramped through th
e superfluid transition from below. The goal of the simulations is to
be able to at least qualitatively, if not quantitatively, predict the
behavior of helium in a reduced gravitational environment. These numer
ical simulations can model helium cells with effective gravitational f
ields of \a/g\ > 0 by changing the distribution of local transition te
mperatures to match the desired gravitational environment. The numeric
al results for the simulated behavior show excellent qualitative agree
ment with the observed experimental data under a variety of effective
gravity values. PACS numbers: 67.40 Pm, 67.40.Kh, 02.60 Lj, 02.70 Bf.
