Summary

IN ORDER TO OBTAIN THE FUNDAMENTAL DATA ON THE HIGH PERFORMANCE ROUGHENED HEATING SURFACE, THE AUTHORS TRIED TO CLARIFY THE AUGMENTATIVE EFFECTS OF A THREE-DIMENSIONAL PROTUBERANCE, WHOSE HEIGHT WAS THE SAME ORDER AS BOUNDARY LAYER THICKNESS. THE LOCAL HEAT TRANSFER CHARACTERISTICS AND FLOW FIELD AROUND A SINGLE AND FINITE LENGTH CIRCULAR CYLINDRICAL PROTUBERANCE HAVE BEEN INVESTIGATED EXPERIMENTALLY. THE MOST EFFECTIVE SHAPE PARAMETER FOR THE AUGMENTATION OF HEAT TRANSFER WAS INDICATED, AND A WAKE FLOW STRUCTURE WAS PROPOSED. AN ARRANGEMENT OF MAXIMUM HEAT TRANSFER COEFFICIENT WAS PRESENTED EXPERIMENTALLY AS A FUNCTION OF SHAPE PARAMETER.
