Sample records for promote rapid mixing. Pacheco, J. Rafael; Ping Chen, Kang; Hayes, Mark A. 2006-08-01. A method for generating mixing in an electroosmotic flow of an electrolytic solution in a three-dimensional channel is proposed. When the width-to-height aspect ratio of the channel cross-section is large, mixing of a blob of a solute in a slip-driven three-dimensional flow in a.
