Summary

THE AUTHORS HAVE NUMERICALLY SOLVED THE GOVERNING EQUATIONS FOR BOTH WATER VAPOUR FLOW AND CONDENSATE FILM FLOW WITH A FINITE DIFFERENCE SCHEME. THE EFFECT OF WAVES APPEARING AT THE VAPOUR-FILM INTERFACE ON MOMENTUM AND HEAT TRANSFER HAS BEEN TAKEN INTO ACCOUNT USING A MODEL PREVIOUSLY PROPOSED FOR THE TWO-COMPONENT TWO-PHASE ANNULAR FLOW HEAT TRANSFER. THE PRESENT NUMERICAL RESULTS ARE COMPARED WITH THE EXPERIMENTAL DATA GIVEN BY BLANGETTI. THE COMPUTED HEAT TRANSFER RESULTS AGREE FAIRLY WELL WITH BLANGETTI'S DATA FOR THE CONDENSATION OF WATER VAPOUR OVER A WIDE RANGE OF FILM REYNOLDS NUMBER, BETWEEN 50 AND 2,000, AND FOR 3 DIFFERENT VAPOUR FLOW REYNOLDS NUMBERS.
