要約

Artificial nucleation sites were drilled in a polished metal surface. The formation of boiling bubbles was studied by electrically heating the surface in saturated distilled water and obtaining surface temperature, heat flux, and photographic data. The surface temperature elevation above saturation required to produce ebullition is given as a function of site radius and compared with three available analyses. Data giving bubble growth as a function of site radius and surface temperature elevation is provided and compared with theoretical growth relations. At bubble detachment the buoyancy and surface tension forces are found to be in good agreement.
