Summary

THE EFFECTS OF A SMALL AMOUNT OF NON-CONDENSABLE GAS ON FILM CONDENSATION OF MULTICOMPONENT VAPOUR MIXTURES ARE ANALYTICALLY STUDIED. THE GOVERNING EQUATIONS OF MASS TRANSFER AND PHASE EQUILIBRIUM OF MULTICOMPONENT SPECIES AT THE LIQUID-VAPOUR INTERFACE ARE SOLVED. GENERALLY, THE OVERALL CONDENSATION RATE IS NOT ALWAYS TO BE DECREASED WITH INTRODUCING THE NON-CONDENSABLE GAS. FOR SMALL TEMPERATURE DIFFERENCE ACROSS THE CONDENSATE LAYER, THE CONDENSATION RATE DECREASES PROPORTIONALLY TO THE MOLE FRACTION OF NON-CONDENSABLE GAS ACCUMULATED AT THE INTERFACE. THE RESULTS ARE APPLIED FOR TWO BINARY SYSTEMS OF CONDENSABLE AND CONDENSABLE SPECIES AS WELL AS CONDENSABLE AND NON-CONDENSABLE SPECIES WITH A NUMERICAL EXAMPLE.
