DROPWISE CONDENSATION AS A TYPICAL FRACTAL GROWTH PROCESS
-
摘要: 本文根据近三十年来在珠状凝结换热研究中积累的实验研究资料,提出珠状凝结是一种典型的分形生长过程。由随机分形模型建立了珠状凝结液滴的尺度分布,应用重整化方法确定了液滴尺度的分布指数。Abstract: The dropwise condensation is a typical fractal growth process, according to the experimental data and conclusions published in last 30 years.The drop size distribution in dropwise condensation is deduced,based on the random fractal model.The fractal dimension index in the size distribution is determined with renormalization method.The analytical results are in good agreement with experimental data.
