  1. Microfluidics Mixing Chamber

  2. Where? / With Whom? Intro to Project Proposal How?

  3. Micro-Fabrication Facility (MFF) • Dr. Michael Khbeis • Kristopher Lawler • Andy Lingley • Class 10000 cleanroom -> Class 100 • 11,500 sqft of wet & dry lab space • Photolithography • Nanolithography • Dry Etch • PVD • CVD • Thermal processing • Metrology

  4. How is microfluidic mixing different? Turbulent [5] Laminar

  5. Reynolds Number[2] • Re = (ρ * V * L) / mu • Dimensionless measure of the ratio of inertia force to viscous force • Inertial forces = density (ρ) * velocity (V) * gradient of the velocity (dV/dx) • Viscous forces = dynamic viscosity coefficient (μ) * second gradient of the velocity (d2V/dx2) • High Reynolds numbers - turbulent mixing • Low Reynolds numbers - mixing relies on diffusion • 0.1 = (1000kg/m3 * 0.0001m * 0.001m/s)[1] 0.001Ns/m2

  6. Passive Microfluidic Mixers[1] • Lamination • Intersecting Channels • Zigzag Channels • Three-Dimensional Serpentine Structures • Embedded Barriers • Slanted Wells • Surface-Chemistry Technology in Microchannels

  7. Laminar mixing [1] • Diffusion limited • Takes time and distance

  8. Intersecting and Zigzag Channels [1] [1]

  9. Three-Dimensional Serpentine Structures and Grooves [1]

  10. Embedded Barriers [4]

  11. Hong Chamber [6]

  12. Questions?
