Rotating Channel Benchmark

A lab-on-a-chip platform can be realized on a rotating disc by designing channels and other features to use the Coriolis or centrifugal forces to manipulate the flow. These forces are controlled by changing the angular velocity of the disc, so the platform is programmed by using a controlled sequence of angular velocities. In a microchannel, the centrifugal force induces a parabolic flow profile ...

Split-Recombine Mixer Benchmark

This example models a split and recombine mixer channel in which a tracer fluid is introduced and mixed by multi-lamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The results compare well with Glatzel et al (Ref 1.) in both the lamination patterns and total pressure drop ...

AC Electrokinetically Enhanced Surface Reactions

This model studies the use of AC electrokinetic forces to enhance the rate of transport of electrolytic reactants to a reaction surface on the wall of a microchannel. If transport was to be governed by flow alone, then the flow velocity perpendicular to the surface would be so small that the analyte would be transported mainly by diffusion. The reaction rate at the surface is large enough ...
