Diagram illustrating the flow of mass between the three gas reservoirs considered in our multiphase G.A.S. model. The star-forming reservoir contains the mass that is immediately available for star formation. It is fed by a turbulent cascade and gas fragmentation at a mass flow rate, Ṁ_sfg (Eq. (18)). The gas reservoir fragments at a rate, Ṁ_frag (Eq. (14)). The diffuse gas reservoir is fed through the rates of two mechanisms: (1) gas accretion rate (Eq. (1)); and (2) the rate at which the fragmented and star-forming gas is disrupted via the energy injected by SNe and AGN, Ṁ_disrupt (Eqs. (27) and (28)). Each of these three gas reservoirs contributes to the outflow rate, Ṁ_wind (Eqs. (24) and (26)).
