A Review on Nucleate Pool Boiling Heat Transfer of Binary Mixtures

Abstract

NPB of many binary mixtures has been studied earlier like methanol-water, ethanol-water, methanol-benzene, acetone-water and isopropanol-water etc. This area of research has been on the rise in the last few years due to its various applications like separation of mixture, chemical engineering and refrigeration etc. This process is used in various industries to increase the energy efficiency which leads to reduction in environmental pollution. Pool boiling of binary mixtures is more complex than boiling of an individual liquid component since it involves mass transfer along with heat transfer. The boiling of binary mixture is immanently complex due to non-uniqueness of boiling point, limited mass transfer and strong variation of mixture properties. The HTC of a binary mixture is known to deteriorate as compared to its individual liquid components. Many co-relations have been developed to determine the HTC but they are only applicable for their own experiment and fail to predict the experimental data of other investigations. This paper aims to provide a brief review of boiling heat transfer of binary mixtures of fluids.
