In this study

a dynamic ice-making system with supercooling water was designed and built

and a visual flat-plate supercooler was developed. The influence of flow and heat transfer on the freezing behavior in the flat-plate supercooler was studied by a large number of experiments

and the mechanism was explained by the classical nucleation theory and boundary layer theory. The results showed that there were two types of freezing behavior in the flat-plate supercooler: freezing behavior 1 shows that no freezing occurs in the supercooler and the system can continuously produce ice slurry

and freezing behavior 2 shows that freezing occurs in the supercooler and the system cannot produce ice slurry. The low inlet temperature of the secondary refrigerant and too large or too small flow of ice-making solutions were largely responsible for promoting the occurrence of freezing behavior 2

which was not conducive to the ice-making stability of the system. When freezing behavior 2 occurs

freezing occurs first on the wall with a relative distance d=0.15

where the temperature is always lower than that of the wall with a relative distance d=0.25

0.35

0.45

so the local condition for freezing to occur first is a lower wall temperature.
