Heat transfer in boiling solutions of liquids

The concept of a pseudoequilibrium process is proposed to describe heat transfer in boiling solutions of liquids. The bubble-formation and bubble-relaxation stages are considered. Either stage is characterized by its own driving force of heat transfer. The concept of the average temperature of a bubble ensemble is introduced to calculate the heat-transfer coefficient at either stage, and a solution is obtained for complete ensembles. A new method for calculating the heat-transfer coefficient is developed. The calculated data are compared with experimental data for 12 systems, including one ternary system.
