AN EXPERIMENTAL INVESTIGATION OF PULSE TUBE REFRIGERATION HEAT TRANSFER RATES.

Author(s) : DAVID M., MARECHAL J. C.

Type of article: Article

Summary

THE AUTHORS PERFORMED EXPERIMENTS TO SHOW THAT THE HEAT EXCHANGES BETWEEN THE GAS AND THE WALLS ARE MORE IMPORTANT IN THE BASIC PULSE TUBE THAN IN THE ORIFICE PULSE TUBE. THEY SHOW THAT THE TUBE RADIUS/DEPTH PENETRATION RATIO CHARACTERIZES THESE HEAT EXCHANGES WELL. THEN, THEY INTRODUCE A NEW CONCEPT OF DESCRIBING PULSE TUBE OPERATION: GAS-GAS HEATEXCHANGES, SHOW QUALITATIVELY THAT THERE MUST EXIST HEAT EXCHANGES ELSEWHERE THAN IN THE HEAT EXCHANGERS, AND DESCRIBE AN EXPERIMENTAL APPARATUS FOR STUDYING THESE PARAMETERS AND FOR OBTAINING GOOD PERFORMANCE. A 85 K TEMPERATURE LIMIT AND A 4-WATT COLD POWER AT 100 K WERE ACHIEVED.
