A NUMERICAL METHOD FOR MULTIDIMENSIONAL FREEZING PROBLEMS WITH ARBITRARY GEOMETRY.

[In Japanese. / En japonais.]

Type of article: Article

Summary

AN EFFICIENT NUMERICAL METHOD FOR MULTIDIMENSIONAL FREEZING PROBLEMS WITH ARBITRARY GEOMETRIES, INCLUDING A MULTIPLE CONNECTED DOMAIN, ARE REPORTED. THE MULTILATERAL ELEMENT METHOD IN WHICH THE REPRESENTATIVE POINT OF THE ELEMENT CAN BE PLACED AT THE ARBITRARY POINT IS PROPOSED. A NUMERICAL METHOD IS PRESENTED IN WHICH THE NEW FREEZING FRONT POSITIONS ARE CALCULATED BY USING TEMPERATURE DISTRIBUTIONS IN THE VICINITY OF THE FREEZING FRONT. THE ADJACENT ELEMENT IS ENLARGED BY THE SAME AMOUNT AS THE NEWLY FROZEN AREA THUS OBTAINED. THIS PROCEDURE IS CONTINUED UNTIL THE SIZE OF THE FROZEN AREA REACHES THE PRESCRIBED SIZE.
