Figure Legend:
Changes along the tube length in the velocity and shear-stress profiles (solid lines) in the deteriorated heat-transfer regimes [44] (CO2; 9.0 MPa; upward flow in 22.7 mm tube: hin=556  kJ/kg, ρu¯=2110  kg/m2 s, qw/ρu¯=0.201  kJ/kg). (1), (2) shear stress and velocity profiles under constant physical properties conditions; (3) limiting τ/τw distribution in the boundary regime of normal heat transfer: (τ/τw)lim≅1−3Y; (4) hypothetical distributions.
