MODELLING OF THE NUCLEATE BOILING OF REFRIGERANT-OIL MIXTURES.

Author(s) : SAIZ JABARDO J. M., SILVA C. L. da

Summary

AN INVESTIGATION OF THE MECHANISM OF NUCLEATE BOILING REFRIGERANT-OIL MIXTURES COULD BE SIGNIFICANT IN THE EVALUATION OF THE NUCLEATE BOILING HEAT TRANSFER CHARACTERISTICS OF POTENTIAL SUBSTITUTES FOR CFCS. IN THIS WORK, A MODEL FOR THE NUCLEATE BOILING OF THE ABOVE MENTIONED MIXTURES IS DEVELOPED, BASED ON THE SUPERPOSITION OF TWO BASIC MECHANISMS: LOCAL AGITATION PROMOTED BY BUBBLES AND HEAT TRANSFER TO THE COLD LIQUID DURING THE WAITING TIME OF THE BUBBLE CYCLE. IT HAS BEEN FOUND THAT THE EFFECT OF THE OIL CAN BE ACCOUNTED FOR BY THE MIXTURE PRANDTL NUMBER. COMPARISON OF THE MODEL RESULTS WITH EXPERIMENTAL ONES OBTAINED BY THE AUTHORS HAS SHOWN SIGNIFICANT CORRELATION. THE ABOVE MENTIONED EXPERIMENTS HAVE BEEN PERFORMED FOR MIXTURES OF R11, R113 AND R114 WITH MINERAL OIL.
