Enhanced Mass Transfer from Rubber Sheet Spargers

研究了橡胶板式喷嘴释放气泡的传质特性。对气泡形成的单孔研究证实了最初的观点，即弹性孔的自我调节对喷嘴释放出的气泡的形成动力学有显著影响。设计了新的实验，生动地展示了弹性膜分离器(Flexisparger)诱导的混合和循环的结构。最初的酸碱实验表明，柔性抛光机会引起漩涡流动。初步工作表明，柔性抛光器在k；1la方面产生了巨大的增强，在轴向混合方面产生了极大的减少。为了测量这些喷雾器产生的气泡的弥散特性、界面面积和传质系数，正在进行更多的实验。

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.
