Disruption of the flow as a function of the filament overdensity, f, and level of turbulence, η. The contours represent constant ratios of t_disrupt∕t_dyn,halo as labeled (cf. Eqs. (5) and (15)). We assume a volume-filling factor of 0.1 (see Fig. 5) for the warm clouds and r_stream = r_vir/10. In regions with values less than 1, the streams are “disrupted” (Sect. 3.3). The shaded region indicates regions that are forbidden because for these values of the parameters, the post-shock pressure is less than the halo pressure. We note that because , the contours of constant t_disrupt∕t_dyn,halo are shaped like contours of constant σ_turb in the same plane. For example, the contour, t_disrupt∕t_dyn,halo = 0.2, is close to the contour for σ_turb = 200 km s⁻¹, which is almost half the initial velocity of the flow.
