Thermal instability in shearing and periodic turbulence

by A. Brandenburg, M. J. Korpi, and A. J. Mee

  • When ρ = 1-5 x 10-24 g cm-3, the system is unstable and segregates into cool and warm phases.
  • Cool patches tend to coalesce into bigger ones.
  • In agreement with earlier results, no sustained turbulence is found.
  • Dissipation rates rates are comparable to the thermal energy input rate.
