Summary

THE CHARACTERISTICS OF MELTING AND SOLIDIFICATION OF A BINARY MIXTURE OF PARADICHLOROBENZENE AND PARADIBROMOBENZENE WERE EXPERIMENTALLY INVESTIGATED IN A HORIZONTAL CYLINDRICAL CAPSULE. SINCE SEGREGATION OCCURS IN THE SOLIDIFICATION AND DENSITY STRATIFICATION OCCURS INTHE MELTING, NON-UNIFORM CONCENTRATION PROFILES WERE FORMED IN BOTH SOLID AND LIQUID PHASES. THESE NON-UNIFORM DENSITY PROFILES GENERATED SEVERAL HORIZONTAL CELLS BY FREE CONVECTION IN THE MELTING PROCESS, WHILE ONLY A FEW LARGE VORTICESWERE GENERATED FOR PURE PARADICHLOROBENZENE. AS A RESULT OF THIS DIFFERENCE OF FREE CONVECTIVE MOTION, HEAT TRANSFER PERFORMANCE OF A BINARY MIXTURE BECOMES SMALLER COMPARED WITH THAT OF PURE MATERIAL.
