TENTATIVE EXPLANATION OF THE ANOMALIES IN THE KAPITZA RESISTANCE BETWEEN SOLIDS AND LIQUID 4 HELIUM II.

Type of article: Article

Summary

ANOMALIES FOUND IN THE MEASUREMENTS OF KAPITZA RESISTANCE WITHIN THE RANGE 2-1 K, ARE STILL ALIVE. BASED UPON EXPERIMENTS WITH SOLID SUPERLEAKS WHICH SHOWED THAT THE PORES, SMALLER THAN 10 NANOMETERS, ARE EMPTY ABOVE THE ONSET TEMPERATURE OF THE SUPERLEAKS, IT IS SUGGESTED THAT FILLING WITH THE SUPERFLUID OF EVENTUAL PORES OR DEFECTS IN THE SOLID BOUNDARY, COULD PROVIDE THE CLUE TO EXPLAIN ANOMALIES. A VARIATION OF THE REAL CONTACT AREA WOULD TAKE PLACE UNTIL THOSE PORES OR DEFECTS ARE TOTALLY FILLED WITH THE LIQUID BY THE ACTION OF THE THERMOMECHANICAL EFFECT.
