Summary

POOL BOILING HEAT TRANSFER WITHIN A CONFINED SPACE WAS STUDIED FOR THE VERTICAL NARROW SPACE BETWEEN PARALLEL HEATED AND UNHEATED PLANES. EXPERIMENTS WERE PERFORMED FOR WATER UNDER ATMOSPHERIC PRESSURE AT A HEAT FLUX RANGE UP TO THE CRITICAL HEAT FLUX. THE GAP SIZE WAS DECREASED FROM 5 TO 0.15 MM IN 4 STEPS AND 2 HEATING SURFACES OF DIFFERENT HEIGHTS WERE TESTED UNDER THE OPEN OR CLOSED PERIPHERY CONDITION OF THE NARROW SPACE. HEAT TRANSFER MECHANISMS WERE DEDUCED AND THE HEAT FLUXES CALCULATED BY PROPOSED MODELS.
