Summary

The transient freezing of water impinging vertically on a subzero disk through a circular jet is studied experimentally to determine the interaction of the fluid flow and the solidification process which is initiated away from the jet (i.e. outside of the hydraulic jump) and moves inward toward the jet. The formation and growth of ice on the cold surface affect the flow field over the surface. The effect of fluid flow on the solidification process is found to be a small reduction in the nucleation temperature. The ice layer profiles at different times for different values of jet Reynolds number, and Stefan numbers of the surface and jet are also measured and reported. An approximate model is developed for the calculation of the transient crust growth. The predicted solid crust profiles are compared with the measured ones.
