International. At the Fraunhofer Institute (Germany), researchers developed new simulation software for water-repellent surfaces for corrosive coatings.
The simulation shows how various liquids work on different surfaces, regardless of whether they are flat, curved or structured. The program simulates the way the liquid behaves on the surface, indicating whether it distributes over that surface or contracts to form droplets to minimize contact with the surface.
The program can also calculate flow behavior in terms of how liquids move across different surfaces, thereby integrating determinants at different measurement scales, from atomic interactions to the impact of the microscopic surface structure.
In addition, the software analyzes what happens within a certain droplet, how individual water molecules interact with each other, and how a droplet is attracted to the surface and resists air.
