Heat transfer and pressure drop were investigated for steam‐water mixtures flowing in an electrically heated horizontal duct of rectangular cross‐section. The investigation was primarily concerned with the region of high vapor fractions and mass flow rates, where two‐phase convention‐controlled heat transfer predominated. The experimental data were found to be in good agreement with those of other studies in which circular tubes were used. The data in the convection‐controlled region were correlated by equations developed from two flow models, a separated‐annular model and a homogeneous model. Two phase pressure drop data were correlated satisfactorily by the Lockhart‐Martinelli correlation.
