Subcooled Flow Boiling Heat Transfer to Mixtures and Solutions

Extensive measurements of subcooled flow boiling heat transfer coefficients have been performed for pure liquids, electrolyte solutions and ternary mixtures of water, isopropanol and acetone over a wide range of concentration, flow velocity, bulk temperature and heat flux. Furthermore convective and subcooled boiling heat transfer coefficients were measured for two complex industrial liquids, namely Kraft liquor from the pulp and paper industry and Bayer liquor from Bauxite refineries. The experimental results are compared with a prediction model combining the Chen model with the Gorenflo correlation and the Schlünder model, for single and multicomponent boiling, respectively.
