✦ Synopsis
The final (steady state) stage of dropwise condensation has been explored using a simple model for droplet deposition and coalescence with the rapid sliding of droplets that exceed a critical size S*. In this steady state regime the mean droplet size and the total mass density both decrease algebraically with increasing distance from the upper edge of the inclined substrate (apart from pronounced oscillations at very shot distances). The droplet number density on the other hand, varies at most logarithmically with this distance. The steady state droplet size distribution can be represented quite well by a stretched exponential form.
