		| Abstract: | 
		The evolution of a cooling flow onto a central dominant galaxy in a galaxy cluster is studied using numerical spherically symmetric hydrodynamic computations. It is argued that the flows may be non-steady, with a short central cooling time and X-ray emitting central temperature maintained by gravitational heating due to the evolution of the cluster potential well. A model for NGC 1275 in Perseus is presented as an example. The model offers the possibility of reconciling the high X-ray inferred mass accretion rates with the severe constraints imposed by optical and radio measurements. |
