Visualization of Vaper Bubble on Subcooled Pool Boiling Heat Transfe from a Horizontal Cylinder

Subcooled Pool boiling heat transfer from a horizontal wire to distilled water is experimentally studied under an atmospheric pressure condition. The horizontal cylinder is made of platinum. Diameter an length of the wire are 0.8 mm and 59.7 mm respectively. The horizontal wire is heated by a D.C. electric power source. Vaper bubbles on horizontal cylinder is photographed by a frash (25μ s) of storoboscope.
