Split and Recombine Mixer Benchmark
Application ID: 14031
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 across the mixer.
