Viscous Fingering in Chromatographic Columns

该项目的目的是促进对固定床中粘性指进的理解。将使用磁共振成像（MRI）在操作柱中原位监测粘性指法。先进的核磁共振技术还将用于直接测量多组分分离过程中的指法，以及颗粒内对流和非均匀分散。手指的行为将与线性稳定性分析得到的理论预测进行比较。

The objective of this project is to advance the understanding of viscous fingering in fixed beds. Viscous fingering will be monitored in situ in operating columns using magnetic resonance imaging (MRI). Advanced MRI techniques will also be employed for direct measurements of fingering during multicomponent separations, and of intraparticle convection and nonuniform dispersion. Finger behavior will be compared with theoretical predictions obtained by linear stability analysis.
