Simulation of the supercooling process and frazil evolution in turbulent flows
MetadataShow full item record
A model to simulate the supercooling process and frazil ice evolution in a counter-rotating flume is developed based on a series of laboratory experiments. The characteristics of the supercooling process were found to be related to air temperature and flow turbulence. Frazil ice growth was observed to follow a log-normal distribution model. The model avoids the need to simulate seeding, secondary nucleation, flocculation-breakup, and gravitational removal. Only the overall heat balance is considered during the entire process. The simulations show good agreements with experimental time-temperature curves and frazil evolution.
