The mass transfer characteristics of bubbles released from rubber sheet         spargers are investigated.  Single hole studies on bubble formation             confirm the original contention that the self-regulation of elastic             holes has a significant effect on formation dynamics of bubbles                 released from the sparger.  New experiments are designed to show in             vivid color the structure of the mixing and circulation induced by an           elastic membrane sparger (flexisparger).  Initial acid base experiments         suggest that flexispargers induce swirl flow.  Preliminary work shows           that flexispargers produce enormous enhancements in k;iLa, and large            reductions in axial mixing.  Additional experiments are being initiated         to measure the dispersion characteristics, the interfacial areas, and           the mass transfer coefficients of bubbles generated by these spargers.
