Real-time investigation of the freezing behaviour of water droplets using Synchrotron-CT in collaboration with the Norwegian University of Science and Technology (NTNU) and the industrial customer Equinor

Last weekend, our team performed real-time investigations of the freezing behaviour of water droplets at PSI's imaging beamline TOMCAT together with NTNU. For the experiment, a tailor-made infrastructure was developed that allows the generation of tiny seawater droplets close to the freezing point. These drops were dropped into a cryochamber onto variously coated surfaces. Using Synchrotron-CT, we are able to study the different freezing behaviour on the coating in three dimensions over time. Equinor's goal is to develop a coating on which sea ice adheres less well.
