Abstract

A simplified model, describing the process of hot coronal gas deposition due to local thermal instabilities in cooling flows, is presented. The effects of the galactic and cluster gravity field are ignored. Two-dimensional numerical hydrodynamic simulations of hot gas evolution reveal an instability of small velocity and/or density perturbations, caused by the gas inelasticity. This instability is shown to be responsible for the formation of correlated filamentary distributions of the hot gas density and the density of deposited matter.
