  We present a simple model for the turbulent kinetic energy behavior of
subsonic plasma turbulence undergoing isotropic three-dimensional compression,
such as may exist in various inertial confinement fusion experiments or
astrophysical settings. The plasma viscosity depends on both the temperature
and the ionization state, for which many possible scalings with compression are
possible. For example, in an adiabatic compression the temperature scales as
$1/L^2$, with $L$ the linear compression ratio, but if thermal energy loss
mechanisms are accounted for, the temperature scaling may be weaker. As such,
the viscosity has a wide range of net dependencies on the compression. The
model presented here, with no parameter changes, agrees well with numerical
simulations for a range of these dependencies. This model permits the
prediction of the partition of injected energy between thermal and turbulent
energy in a compressing plasma.
