Drop distributions and numerical simulation of dropwise condensation heat transfer

Molecular clustering physical model of steam condensation and the experimental study on the initial droplet size distribution

“…It was considered that there were two simultaneously reverse processes, condensing and evaporating, on the nucleus surfaces. Only when the condensing rate was larger than the latter, the droplet could grow up; the droplet size at this moment was called the minimal size, which could be calculated by Kelvin theory [6][7][8]. Subsequently, the droplet growing process was divided into two stages [9], mainly through direct condensation on it self's surface and mainly through the coalescence between droplets, by the critical size.…”

“…Subsequently, Mousa [6], Vemuri and Kim [7] developed the small droplet size distribution based on the work of Wu and Maa [15]. Wu et al [8] put forward a random fractal model to simulate the size and spatial distribution from the primary to the departing droplets in dropwise condensation. Lan et al [16] rebuilt the spatial conformation of droplet distribution into the temporal conformation based on the random fractal model and reflected the dynamic characteristics of dropwise condensation and developed the dropwise condensation heat transfer model with the liquid-solid surface free energy difference effect.…”

Effects of surface topography of material on nucleation site density of dropwise condensation

“…Wu et al (2001) and Yang et al (1998) studied the fractal character of dropwise condensation. They indicated that the droplet distribution of dropwise condensation appeared with self-similarity, one of the most important features of fractal.…”

Droplet condensation on polymer surfaces: A review

“…96 Wu et al simulated drop size and spatial distributions with high precision by using the random fractal model and their numerical simulation results were in good agreement with the bulk of existing experimental data. 97 Ulrich et al simulated the homogeneous deposition of liquid droplets having a 90…”
