Uplifted cool gas and heating by mixing in cooling flows
  We analyze our earlier three-dimensional hydrodynamical numerical simulation
of jet-inflated bubbles in cooling flow clusters, and find that dense gas that
was not heated by the jets' activity and that resides around the hot
jet-inflated bubbles can be identified as uplifted gas as observed in some
clusters. During the build up of the dense gas around the hot bubble, mixing of
hot bubble gas with other regions of the intracluster medium (ICM) heats the
ICM. The vortices that mix the ICM with the hot bubble gas also excite shock
waves, sound waves, and turbulence. Sound waves, shocks, turbulence, and
uplifted gas, might be easier to detect than the mixing process and hence
attract more attention, but we argue that the contributions of these processes
to the heating of the ICM do not add up to the level of contribution of the
mixing-heating process.
