Condensation and Freezing Front Propagation on Surfaces With Topographic and Chemical Modifications

Experimental data on propagation were reported for a freezing front crossing on micro-grooved substrates in a 200mum-to-400mum-thick water layer. The speed of a freezing front oscillates locally over the grooves, with propagation retarded in troughs and accelerated on crests. When the water freezing point moves at a constant speed, the speed of a freezing front on crests can be more than 8 times the speed in troughs. A numerical estimation shows that the difference of the propagation speeds on crests and in troughs is mainly caused by thermal effects.
