Abstract
The role of heat conduction in the cooling flows of clusters of galaxies has been investigated by running a series of numerical hydrodynamic computations. It is found that flows with no source or sink develop a cold and dense condensing core inconsistent with X-ray observations, while including a sink for the cooling gas produces a gradual drop in temperature toward the cluster center in agreement with X-ray measurements. Heat conduction can suppress the accretion rate by a factor of a few to several, while larger reductions result in a nearly isothermal Intra-Cluster Medium.
