Figure 8: The advection factor (ratio of advective to radiative cooling) profiles for m˙ = 0.01, 1.0 and 10.0 (here, m˙ = M˙ c2∕16L Edd). Profiles for α = 0.01 and 0.1 are presented with solid black and dashed red lines, respectively. The fraction fadv∕(1 + fadv) of heat generated by viscosity is carried along with the flow. In regions with fadv < 0 the advected heat is released. Image reproduced by permission from [269].
