文摘

Developed a constrained optimization approach for maximization of mixing due to electro-osmosis. Dynamic voltage inputs (amplitude, phase and frequency) that maximize mixing are determined. Developed an infinite-dimensional system to describe the relationship between hydrodynamics and electro-osmotic slip velocities. Constructed a virtual output that allows for hydrodynamic mixing maximization to be conducted in the frequency domain. The effects of Reynolds number, electrode size, spacing, and number of electrodes were studied.
