Flow Simulation of a Microfluidic Analog of the Four-Roll …

desired functionality is the four roll mill. While this is primarily thought of as a device for producing planar extension (ξ = 1), it can also be used to provide mixed flows with 0.2 < ξ < 1 [7-8], and rotational flows where ξ ~ -1 [9]. However, the four roll geometry cannot produce simple shear (ξ …

Flow Simulation of a Microfluidic Analog of the Four-Roll Mill

A pressure driven microchannel device is sought that has an adjustable flow type, approximating the function of the four-roll mill.
