Abstract

We have performed numerical simulations of the behavior in a one-dimensional thermal conductivity cell of helium as it is ramped through the 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 numerical simulations can model helium cells with effective gravitational fields of |a/g| > 0 by changing the distribution of local transition temperatures to match the desired gravitational environment. The numerical results for the simulated behavior show excellent qualitative agreement with the observed experimental data under a variety of effective gravity values.
