Velocity profiles exhibiting maxima away from the axis of symmetry have been calculated for supercritical carbon dioxide flowing vertically in a heated circular duct. The analysis was carried out at the two-dimensional level and the turbulent fluxes are represented by a two equation model of turbulence. The existence of such velocity profiles has been accepted previously but the nature of their growth along a pipe was not known previous to this work.
