Local heat transfer coefficients were carefully measured for the nitrogen dioxide‐nitrogen tetroxide system in well‐developed turbulent flow in an electrically heated, 0.194‐in. I.D. tube. The average probable error determined from reproducibility tests was less than 2%. The modification of the Deissler analogy presented earlier ( 8 ) was found to predict coefficients which agreed well (0 to 19% deviation) with the observed results. Some of this deviation may be due to uncertainties in the viscosity data. Brokaw's viscosity information ( 1 ) gives results that were higher than the experimental values, but that of Thievon et al. ( 11 ) would have given low values. The data were also compared with a simpler Colburn type of analogy in which a heat transfer coefficient based upon enthalpy was employed. The deviations here were larger.
