In a microfluidic ultrasonic separator device, the microchannel geometry is inherently angular due to the anisotropic etch processes used. A CFD model is used to investigate eddy formation induced by this angular geometry. Results are applicable to various microfluidic devices and show that certain etch patterns significantly reduce eddy formation.
