Researchers from Skoltech (Russia) and their colleagues from SINTEF (Norway) have developed a mathematical model of freezing water droplets moving in cold air. This model is a part of a joint RFBR-supported Russian-Norway research project. The project is focused on predicting ice accretion on ships and other offshore structures operated in Arctic climate, which may interfere with their proper functioning and endanger crew members and cargo. The paper was published in the journal
Energies.
Ships travel in cold northern waters under constant bombardment by tiny water droplets populating the chilly air. The droplets are expelled into the air at the impact of sea waves on the ship hull or other surfaces. When they reach the ship s substructure, these semi-frozen droplets can either bounce off or stick. The probability of the droplets sticking to the wall depends on their freezing state, i.e., completely frozen droplets simply bounce off, while others lead to different scena
