SURFACE TENSION EFFECTS ON CONVECTIVE BOILING HEAT TRANSFER IN COMPACT HEAT EXCHANGERS WITH OFFSET STRIP FINS.

Type of article: Article

Summary

PREVIOUS WORK HAS INDICATED AN UNEXPECTED FACTOR IN BOILING HEAT TRANSFER AT LOW FLOW RATES IN OFFSET STRIP FIN HEAT EXCHANGERS. INSTEAD OF DECREASING TOWARDS THE VALUE FOR SINGLE-PHASE LIQUID FLOW, THE COEFFICIENT APPEARS TO REACH A MINIMUM AT ABOUT TWICE THE EXPECTED VALUE. THE PAPER OFFERS THE SUGGESTION THAT THIS IS DUE TO SURFACE TENSION HOLDING BACK VAPOUR BUBBLES WITHIN THE FIN MATRIX, CREATING A FORM OF SLUG FLOW. A PROOF IS PRODUCED AND A MODEL CREATED FOR THE PREDICTION OF THIS EFFECT. D.W.H.
