Summary

THE STUDY AIMS TO INVESTIGATE THE ROLE OF LATENT HEAT TRANSFER, IN CONNECTION WITH THE VAPORIZATION OF A THIN LIQUID FILM ON A TUBE'S INSIDE SURFACE, IN NATURAL CONVECTION FLOWS DRIVEN BY THE SIMULTANEOUS PRESENCE OF COMBINED BUOYANCY EFFECTS OF THERMAL AND MASS DIFFUSION. RESULTS ARE PRESENTED FOR AN AIR-WATER SYSTEM. THE EFFECTS OF TUBE LENGTH AND SYSTEM TEMPERATURES ON THE MOMENTUM, HEAT AND MASS TRANSFER IN THE FLOW ARE EXAMINED IN GREAT DETAIL. THE IMPORTANT ROLE THAT THE LIQUID FILM PLAYS UNDER THE SITUATIONS OF BUOYANCY-AIDING AND OPPOSING FLOWS IS DEMONSTRATED.
