Abstract

The behavior of bubbles in a vessel under reduced pressure was observed and the volumetric mass transfer coefficient was measured using a water model. The average diameter of the bubbles immediately after breaking away from the orifice increased with increasing gas flow rate corrected by the pressure at the orifice. An empirical equation for the volumetric mass transfer coefficients under normal and reduced pressures was developed, which can represent previous work using a water model.
