Abstract

Surfactant effects on boiling incipience and single vapor bubble growth dynamics were systematically studied in a poll boiling apparatus for sodium dodecyl sulfate, aerosol-22, DTMAC, and triton X-100. The values of incipient superheat ΔTincip were determined by measuring the incipient wall temperatures over the identified target cavities on a tubular heater. By analyzing the films, in which ebullition cycles over identified target cavities at a low heat flux were photographed by using a high speed camera, frame by frame, the values of waiting period tw, growth rate dr/dt, and departure diameter d were evaluated.
