A New Correlation to Predict Nucleate Boiling Heat Transfer Coefficient of Binary Mixtures

Boiling has long played a significant role in many technological applications due to its superior heat transfer performance. The complexities encountered in the boiling process have stimulated numerous investigators to conduct extensive research in this field. Boiling of pure components has been well established, while the boiling of mixtures has been studied in less detail. The evaluation of the heat transfer coefficients requires the development of elaborate models and experiments due to the complexity of nucleate boiling mechanism. During the last 30 years many correlations have been proposed as a result of the intensive researches on the nucleate boiling mechanism. In this article, a new correlation has been developed on the basis of correlation of Stephan and Körner which is known as a successful correlation for the prediction of nucleate boiling heat transfer coefficient of mixtures. Comparison of the prediction of new correlation with experimental data indicates that this modification can improve the performance of Stephan and Körner correlation.
