Saturated and Subcooled Pool Boiling Heat Transfer in Mixtures of Water and Glycerin
Original language description
Heat transfer coefficient (HTC) was experimentally measured for saturated and subcooled pool boiling of binary mixtures of water and glycerin. Saturated boiling was studied for mixtures with water mass fractions ????w from 100% to 60% on horizontal flat nickel-plated surfaces at heat fluxes from 50 to 650 kW/m2 at atmospheric pressure. Subcooled boiling was investigated in the range of subcooling from 0 to 30 K at heat fluxes of approximately 250, 450 and 650 kW/m2. It was found that mixture effects have a significant impact on saturated boiling HTC even for mixtures with very low content of glycerin as significant drops of HTC were observed for subtle changes in composition for mixtures of high ????w. Measured HTC was successfully correlated with the combination of Yagov (1999) and Inoue and Monde (2009) correlations with a mean relative error of 12%. A simple empirical HTC correlation is also proposed. For subcooled boiling, developed subcooled boiling regime was reached for all investigated heat fluxes. For this regime, correlations which were able to predict HTC for saturated boiling were employed to predict subcooled boiling HTCs for all investigated concentrations, heat fluxes and subcoolings. Effect of subcooling and effect of liquid composition on total HTC were of the same importance for mixtures with higher water content. With increasing concentration of glycerin in the mixture, decrease of total HTC with increasing subcooling became more significant.
