Experiments on Bubble and Droplet Production in Falling Jets and Breaking Waves
The development of research and exploration in Arctic waters is very common nowadays. One of the environmental difficulties to carry out research in these regions is the icing of surfaces. After short periods of time, ice can form in thick layers on the surface of vessels, ships and oil platforms. T...
