چکیده

Boiling of pure components has been well discussed in the literature, while the boiling of solutions has been studied in less detail due to its high complexity. In this investigation, a large number of experiments have been performed to measure the nucleate boiling heat transfer coefficients of water/diethanolamine (DEA) and water/monoethanolamine (MEA) binary solutions. Based on our experimental data, effects of different physical properties such as surface tension, viscosity and density of solutions on nucleate boiling heat transfer coefficients and also on bubble dynamics have been discussed. Furthermore, 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 solutions. Comparison of the prediction of new correlation with our experimental data indicates that this modification can significantly improve the performance of Stephan and Körner correlation.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
