管片式换热器冷凝排水数学模型研究

Based on the mathematical analysis, a numerical model of condensate drainage of plain-fin-and-tube heat exchangers under off-cycle condition is established. The model can present the dynamic characteristics of condensate drainage. Effects of the geometric parameters and materials on the condensate drainage are studied. The numerical data agree with the experimental data very well, which can help engineers in the plain-fin-and-tube heat exchangers design and optimization.
