Subcooled boiling of binary mixtures under conditions of forced convection

Heat transfer during forced convective subcooled boiling of three binary mixtures was experimentally studied in a boiling loop at different liquid velocities, degress of subcooling, and concentrations of the mixture. It was noted that the higher the concentration of the more volatile component in the binary mixture, the higher is the degree of superheat required for a given heat flux. The eexperimentally determined heat transfer coefficients were satisfactorily correlated by using the dimensionless parameters suggested for forced convective subcooled boiling of pure liquids and by incorporating a heat and mass transfer correction factor to account for the additional resistance due to simultaneous mass transfer. © 1990.
