U.S.- United Kingdom Cooperative Research: Three-Phase Fluidization Research

该奖项将支持俄亥俄州立大学范良石博士和英国剑桥大学J.F.戴维森博士在化学工程方面的合作研究。该项目的目标是确定涉及低密度颗粒的三相流态化的输送行为。这项研究将重点放在固定了活微生物的非刚性生物制品上。范博士目前在俄亥俄州立大学的研究项目主要涉及三相流态化中的流体动力学和轴向液体混合，涉及聚苯乙烯、醋酸酯、丙烯酸和尼龙等低密度刚性颗粒。这项拟议的工作将补充剑桥大学正在进行的积极研究计划，该计划强调三阶段生物流态化。在访问剑桥期间，范博士将研究生物颗粒的流体力学和轴向液体混合，例如海藻酸钙颗粒和固定在细胞上的活性碳颗粒。根据实验结果，总结了颗粒特性对三相流态化的影响。本研究将有助于了解三相流态化在生物处理中的应用。

This award will support cooperative research in chemical engineering between Dr. Liang-Shih Fan, Ohio State University, and Dr. J.F. Davidson, University of Cambridge, England. The objective of the project is to define the transport behavior of three-phase fluidization involving low density particles. The research will focus on non-rigid bioparticles immobilized with living microorganisms. Dr. Fan's current research program at Ohio State University is concerned primarily with the hydrodynamics and axial liquid mixing in three-phase fluidization, involving rigid particles of low densities such as polystyrene, acetate, acrylic and nylon particles. The proposed work will complement the active ongoing research program at the University of Cambridge, which emphasizes three-phase biofluidization. During his visit to Cambridge, Dr. Fan will investigate the hydrodynamics and axial liquid mixing involving bioparticles such as calcium alginate particles with and without entrapment of cells and activated carbon particles immobilized with cells. Effects of particle properties on three-phase fluidization will be generalized based on the results of the experiments. This research will contribute to the understanding of three-phase fluidized bed applications in biological processing.
