Modeling of a Microfluidic Analog of the Four-Roll Mill for Materials Characterization
Frederick R. Phelan Jr., Steven Hudson
The fluid dynamics of channel geometries for liquid state materials characterization in microfluidic devices are investigated. A pressure driven microchannel device is sought that has an adjustable flow type, approximating the function of the four-roll mill. In particular, classes of channel flows in which the full range of linear flows (extension, shear and rotation) can be approximated in the neighborhood surrounding a stagnation point are investigated using finite element flow simulation and flow classification criteria. A class of flow geometries is identified which makes use of opposing, laterally offset fluid streams that produce a stagnation point in the center of the geometry.
