Abstract

Abstract

the Based on the typical characteristics of the restricted bubble, the geometric structure of confined bubble flow is investigated. Based on the time weighted average method, the weights of the confined bubble and the liquid plug area in the confined bubble flow are determined. Based on one-dimensional heat conduction theory and integral method, a method for calculating the evaporation heat transfer coefficient of liquid film was established and applied to the annular flow area.The model works with Re range of 2300 to 5373, Pr range of 2.75 to 19.8, and Ca range of 0.000835 to 0.002767.
