BOILING REGIMES IN A CLOSED TWO-PHASE THERMOSIPHON.

Author(s) : NIRO A., BERETTA G. P.

Type of article: Article

Summary

EXPERIMENTALRESULTS AND AN ANALYTICAL MODEL ON THE BOILING MECHANISMS IN A CLOSED TWO-PHASE THERMOSIPHON ARE PRESENTED IN ORDER TO DEFINE THE FRONTIER BETWEEN INTERMITTENT BOILING AND FULLY-DEVELOPED BOILING. THE BOILING REGIMES ARE CLASSIFIED ON THE BASIS OF THE FREQUENCY OF BUBBLE NUCLEATION AND THE RATIO OF BUBBLE DIAMETER TO DEVICE DIAMETER. A CRITERION FOR THE INTERMITTENT DEVELOPED-BOILING FRONTIER IS BASED ON THE RATIO OF THE BUBBLE-NUCLEATION WAITING TIME AND THE BUBBLE GROWTH TIME. A CORRELATION BETWEEN POWER THROUGHPUT, WORKING-FLUID PRESSURE AND NUCLEATION CRITICAL SUPERHEAT IS OBTAINED.
