High-speed motion pictures were taken of initial pool boiling of carbon tetrachloride using a schlieren optical system and associated temperature instrumentation. Many bubbles leaving the heat source were found to be superheated regardless of the degree of subcooling of the liquid. Individual bubbles rising from the heater surface carried a thin laminar layer of hot liquid on their upper surface and trailed a wake of warm liquid. An idealized model of the surrounding warm liquid was empirically developed and accounts for a significant portion of the heat transfer in pool boiling of highly subcooled liquid.
