J. Rafael Pacheco ASU Mechanical and Aerospace Engineering P.O. Box 876106, Tempe, AZ 85287-6106 Efficient and rapid mixing in a slip-driven three-dimensional flow in a rectangular channel Abstract Mixing of a blob of a solute in a slip-driven three-dimensional flow in a rectangular channel is studied. For large width-to-height aspect ratio channels, this serves as a good model for mixing in electroosmotic flows in a three-dimensional channel. It is demonstrated that under certain conditions, efficient and rapid mixing can be achieved. A method to implement this operating condition in electroosmotic flow is also proposed. Biosketch J. Rafael Pacheco received his Ph.D. in Mechanical Engineering at Arizona State in 1999, his M. Sc. in Mechanical Design at the Universidad de Guanajuato and his B.Sc. in Mechanical and Electrical Engineering at the Universidad Iberoamericana in Leon Mexico. From 199 to 2001 he was a visiting assistant professor in the Department of Mathematics at Arizona State University. He currently works in the Industrial Assessment Center at Arizona State University.
