Summary

ACCORDING TO HEAT AND MASS TRANSFER MECHANISM IN POROUS LAYERS , THE KNOWLEDGE OFNUCLEATE POOL BOILING FROM SINTERED POROUS SURFACES IS REPORTED. THE BOILING HEAT TRANSFER COEFFICIENT OF POROUS SURFACES IS ENHANCED APPROXIMATELY 3-10 TIMES THAT OF SMOOTH SURFACES. THROUGH EXPERIMENT, THE AUTHORS OBTAINED RESULTS SHOWING THAT THE DISTANCE BETWEEN 2 TUBES MAKES IMPACT ON BOILING HEAT TRANSFER OF POROUS SURFACES. THEY OBSERVED THAT THERE IS A HYSTERESIS PHENOMENON WHEN POROUS SURFACES ARE SUBMERGED IN LIQUID NITROGEN.
