    Notizen: Holographic techniques employing a pulse ruby laser were used to measure the size and velocity of drops for air-water two-phase critical flow at quality levels above 0.95. The use of a large numerical aperture in the holographic recording system permitted diffraction limited resolution of the droplets. The measured slip ratio a long withthe observation that a very significant portion of the liquid phase was concentrated near the boundary layer at the exit plane indicates that a separated flow model describing two-phase critical flow would represent the actual conditions to a better degree than the other models.

    Unsteady state mass transfer from gas bubbles - liquid phase resistance (1965)
    Hoboken, NJ : Wiley-Blackwell

    Notizen: Liquid phase mass transfer coefficients were determined for streams of bubbles of pure oxygen, 10% carbon dioxide in air, and 10% chlorine in air all rising in water. The results were compared with coefficients predicted by Higbie's equation for unsteady state diffusion into transient films. The observed coefficients for oxygen and carbon dioxide were slightly higher than predicted. The experimental absorption coefficients based on the free chlorine concentrations were in good agreement with the predictions assuming simultaneous irreversible reaction with the transient water film and a pseudo first-order reaction rate constant of 13.7 sec.-1.
