Summary

SINCE THE THERMODYNAMICS OF BINARY MIXTURES CAUSES DIFFERENT COMPOSITIONS IN THE LIQUID AND VAPOUR PHASES, THE MASS TRANSFER NEAR THE GAS-LIQUID INTERFACE AFFECTS THE HEAT TRANSFER WITH PHASE CHANGE. FOR POOL BOILING OF BINARY MIXTURES, SEVERAL PREDICTIVE METHODS HAVE BEEN PROPOSED. THE METHOD OF THOME SEEMS TO BE ACCEPTABLE. FOR FLOW BOILING, HEAT TRANSFER IS SIGNIFICANTLY REDUCED IN THE LOW-QUALITY REGION, IN WHICH NUCLEATE BOILING IS THE MAIN HEAT TRANSFER MECHANISM. THE ACCURACY OF PREDICTIVE METHODS IS ABOUT 20%.
