Suppression of Nucleate Boiling of Pure and Mixed Refrigerants in Turbulent Annular Flow



H. D. Ross, R Radermacher


The following issues are addressed: (a) Is suppression of nucleate boiling an appropriate physical mechanism to explain experimental heat transfer coefficient behavior? (b) Is suppression possible under reasonable conditions with refrigerants? (c) Is suppression more or less likely with a binary mixture of refrigerants as compared with either pure fluid? Issue (a) is resolved in favor of traditional suppression theory by critical review of the literature. Issue (b) is resolved by experimental evidence suggesting one must have rather low pressures to suppress nucleation with refrigerants. Issue (c) is resolved by experimental and correlative evidence suggesting systematic differences with mixtures.
