Bubbles as tracers of heat input to cooling flows.
BINNEY J., ALOUANI BIBI F. and OMMA H.
Abstract (from CDS):
We examine the distribution of injected energy in three-dimensional, adaptive-grid simulations of the heating of cooling flows. We show that less than 10 per cent of the injected energy goes into bubbles. Consequently, the energy input from the nucleus is underestimated by a factor of order 6 when it is taken to be given by PVγ/(γ - 1), where P and V are the pressure and volume of the bubble, and γ is the ratio of principal specific heats.
