OPTIMAL THERMAL DESIGN OF A HIGH TEMPERATURE SUPERCONDUCTING CURRENT LEAD.

Author(s) : SEKULIC D. P., UZELAC Z., EDESKUTY F. J.

Summary

THE PAPER PRESENTS RESULTS OF THE ANALYSIS OF THE HEAT TRANSFER PHENOMENA AND THE CORRESPONDING THERMODYNAMIC IRREVERSIBILITY IN A HIGH TEMPERATURE SUPERCONDUCTING CURRENT (HTSC) LEAD (THE COMPOUND YBCO). THE THERMODYNAMIC IRREVERSIBILITY CAUSED BY HEAT CONDUCTION INCLUDING OR EXCLUDING HEAT GENERATION AND/OR HEAT CONVECTION THROUGH A HTSC LEAD HAS BEEN INTERPRETED BY THE ENTROPY GENERATION OBJECTIVE FUNCTION. IT HAS BEEN SHOWN THAT THE OPTIMAL THERMAL DESIGN IS ATTAINABLE. BOTH NON-LINEARIZED AND LINEARIZED CASES OF VAPOR-COOLED CURRENT LEAD IN NON-IDEAL COOLING CONDITIONS HAVE BEEN CONSIDERED. THE PROBLEM HAS BEEN ANALYZED IN A STEADY STATE SITUATION. A SET OF LINEARIZED DIFFERENTIAL EQUATIONS AND CORRESPONDING BOUNAR CNIN S T LAPLACE TRANSFORM TECHNIQUE WHILE THE NON-LINEARIZED CASE HAS BEEN ANALYZED BY APPLYING A NUMERICAL METHOD.
