ME536 Tags, SLN 23770
Time: M,W 3:30-4:50, SMI 105
Instructor: Jonathan D. Posner
This course focuses on fundamental fluid transport physics at the micron and nanometer scale. The concepts covered in the class are critical to understanding the physics of micro and nanofluidic devices as well as other small-scale fluid systems such as biosensors, colloids, nanomotors, and biological systems. At small length scales fluid motion and transport is governed by electromagnetic, interfacial (surface tension), and stochastic phenomena that differentiate these flows from typical macroscale flows. In microfluidic devices these phenomena enable new and high-performance separation, concentration, control, and diagnostic processes. This course will cover Newtonian fluid mechanics, mass transfer, charged double layers, electrokinetically driven flow and transport (electroosmosis, electrophoresis, dielectrophoresis), surface tension. Additional topics can be discussed depending on student interest.
This course is open to students in all engineering disciplines (mechanical, bio, chemical, materials, electrical) as well as those in chemistry, physics, and life sciences. The course is 3 hours of lecture per week and will have midterm and final exams, and some homework.
Prerequisites: Fluid mechanics or some transport phenomena are strongly recommended, consult with the instructor (jposner@uw.edu)
