Droplet condensation and film condensation. Droplet-like condensation forms small droplets that fall directly down along the wall surface
Droplet condensation and film condensation; in droplet condensation, small liquid droplets fall straight down along the wall
Droplet condensation and film condensation. Droplets condense into small droplets that fall directly down along the wall surface.
Dropwise condensation and filmwise condensation. In dropwise condensation, small droplets fall directly down along the wall surface
Reply to 1# shmily327: For water cooling and air cooling, water has a higher specific heat capacity, which allows it to absorb more heat; hence, its cooling effect is better
Reply to 1# shmily327: Heat exchange, mixing； Mixing can make full use of the steam potential
There are two ways of steam condensation: droplet condensation and film condensation. Among them, since the droplets condense into small droplets that fall directly along the wall surface, its heat transfer efficiency is high.
Cool down, increase pressure； High thermal conductivity
It is divided into film condensation and droplet condensation. In droplet condensation, since the condensed liquid cannot form a complete film to separate the steam from the wall surface, most of the cold wall is exposed directly to the steam; as a result, the thermal resistance is much lower and heat transfer is more efficient.
