Summary

THE MASS DIFFUSION PROCESS CREATED BY THE COMPOSITION DIFFERENCE BETWEEN THE VAPOUR AND LIQUID PHASES WAS FOUND TO IMPEDE THE BOILING PROCESS AND SUBSTANTIALLY REDUCE THE NUCLEATE BOILING HEAT TRANSFER CONTRIBUTION TO FLOW BOILING IN MIXTURES. TWO WIDELY QUOTED BOILING MIXTURE CORRECTION FACTORS WERE TESTED AGAINST A PUBLISHED SET OF EXPERIMENTAL DATA FOR ETHANOL/CYCLOHEXANE MIXTURES AND WERE DETERMINED TO BE ONLY PARTIALLY RELIABLE. INSTEAD, SEVERAL THEORETICALLY BASED NUCLEATE POOL BOILING MIXTURE CORRELATIONS WERE SHOWN TO BE ACCURATE FOR FLOW BOILING CONDITIONS AND ARE RECOMMENDED FOR DESIGN USE.
