215 Observation of Vaper Bubbles of Subcooled Boiling Heat Transfer : Nucleate Boiling and Critical Heat Flux Point
Details
Pool boiling heat transfer from a horizontal cylinder to the distilled water is experimentally studied under the atmospheric pressure condition. The horizontal cylinder is made of platinum. The horizontal cylinder is heated by a D.C. electric power source. Critical heat flux on the subcooled boiling are obtained by electric power source for the horizontal cylinder. Vaper bubbles on the horizontal cylinder are photographed with a single reflex camera by a flash. Under subcooled boiling conditions, the following phenomena are observed: many small vaper bubbles are observed on the surface of the horizontal cylinder.
