Summary

WATER IN A VERTICAL ANNULUS IS FROZEN FROM THE INNER CYLINDER WALL. THE OUTER CYLINDER WALL IS INSULATED. THE WATER WAS 150 MILLIMETERS HIGH AND THE DIAMETERS OF THE INNER AND OUTER CYLINDERS WERE 20 AND 100 MILLIMETERS. A BOUNDARY FIXING METHOD WAS USED AND THE TWO-DIMENSIONAL UNSTEADY NATURAL CONVECTION IN THE LIQUID PHASE WITH DENSITY INVERSION WAS CALCULATED. THE ANALYTICAL RESULTS OF THE TIME-WISE CHANGES OF THE FREEZING FRONT AND THE TEMPERATURE DISTRIBUTION AGREED WELL WITH THE EXPERIMENTAL RESULTS. A ONE-DIMENSIONAL APPROXIMATE ANALYSIS WAS CARRIED OUT, WHERE THE APPROPRIATE HEAT-TRANSFER COEFFICIENT ON THE FREEZING FRONT WAS GIVEN.
