Summary

NUCLEATE BOILING WITHIN AN ANGULAR GEOMETRY, A BASIC GEOMETRY FOUND IN MANY STRUCTURED BOILING HEAT TRANSFER SURFACES, IS INVESTIGATED. POOL BOILING TESTS ARE CONDUCTED USING WATER AT ATMOSPHERIC PRESSURE AND A HORIZONTAL HEATED WALL WITH AN INCLINED WALL ATTACHMENT MAKING A LINE CONTACT TO FORM AN ANGULAR GEOMETRY. IT IS FOUND THAT NUCLEATE BOILING FROM THE HORIZONTAL HEATED WALL IS GREATLY ENHANCED BY A FAVORABLE THERMAL ENVIRONMENT WITHIN THE ANGULAR GEOMETRY. THE EFFECTS OF THE ANGLE BETWEEN THE 2 WALLS, AND ROUGHNESS AND LENGTH OF THE WALL ATTACHMENT ARE STUDIED. THE RESULTS REVEAL THE IMPORTANCE OF THE ANGULAR GEOMETRY TO THE ENHANCED NUCLEATE BOILING HEAT TRANSFER OF STRUCTURED SURFACES.
