Influence of Cooling Flow and Galactic Motion on the Iron Distribution   in Clusters of Galaxies
  Iron abundance distribution is now known for 12 clusters of galaxies. For some clusters (e.g. Centaurus) the observed abundance increases toward the cluster center, while for the others (e.g. Coma and Hydra-A) no significant inhomogeneity was observed. In order to understand this difference, we investigate the influence of cooling flow and turbulence produced by galactic motion on the iron abundance distribution by simple spherical models. We show that the cooling flow has a significant effect to flatten the iron abundance distribution if the flow velocity is sufficiently large. Further, by applying our analysis to the above clusters we show that we can give a systematic account for the observed variety of the iron abundance distribution qualitatively.
