An Experimental Study on Supercooling Phenomena in Water Saturated a Solid Angle

Supercooling phenomena with pure water in freezing process was studied experimantally from -5℃ to 0℃. Temperature distribution and heat transfer were analyzed on the supercooling phenomena according to the initial temperature, inclined angle and temperature of cooling wall were varied. When the water was cooled from the cooling surface, a supercooling phenomena was appeared. After a while dendrictic ice grew sudenly and dense ice layer began to grow from the surface. The supercooling phenomena duration was the longer with decreasing the inclined angle and initial temperature than those of increasing the inclined angle.
