Summary

AN INVESTIGATION IS CARRIED OUT ON HEAT TRANSFER BY DIRECT CONTACT CONDENSATION AT A STEAM-SUBCOOLED WATER INTERFACE IN A HORIZONTAL RECTANGULAR CHANNEL. THREE TYPESOF MODELS ARE USED TO PREDICT THE HEAT TRANSFER COEFFICIENT AT THE INTERFACE. THE HEAT CONDUCTION MODEL IS USED TO ESTIMATE THE LOWEST LIMIT OF HEAT TRANSFER. THE MODIFIED MODEL, WHICH SIMULATES THE NEAR-INTERFACE VARIATION OF THE TURBULENCE QUANTITIES, SHOWS THE MORE IMPROVED PREDICTION COMPARED WITH THE WALL MODEL AND AGREES WITH THE EXPERIMENTAL RESULTS WITH SMOOTH INTERFACES THE EXPERIMENTAL RESULTS WITH INTERFACIAL WAVES ARE PREDICTED QUANTITATIVELY BY INTRODUCING THE INTERFACIAL WAVE EFFECT INTO THE SURFACE RENEWAL MODEL.
