Enhanced Mass Transfer from Rubber Sheet Spargers

研究了橡胶薄板喷射器释放气泡的传质特性。对气泡形成的单孔研究证实了弹性孔的自我调节对喷射器释放的气泡形成动力学有重要影响的原始论点。设计了新的实验，生动地展示了弹性膜分离器（flexisparger）引起的混合和循环结构。初步的酸碱实验表明，柔性纤维可引起旋流。初步的研究表明，弹性包在k；和轴向混合的大量减少。正在进行额外的实验，以测量这些喷射器产生的气泡的弥散特性、界面面积和传质系数。

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.
