Optimization of the Herringbone Type Micromixer Using Numerical Modelling and Validation by Measurements - new

E. Tóth[1], K. Iván[1], P. Fürjes[2]
[1]Pázmány Péter Catholic University, Budapest, Hungary
[2]Research Centre for Natural Sciences Institute for Technical Physics and Materials Science Hungarian Academy of Sciences, Budapest, Hungary

COMSOL Multiphysics® software was used in this study to simulate mixing by diffusion and by secondary flow. Particle tracing model was applied to simulate the mixing of cells in the microchannel. Results agreed well with the measurement, an optimal herring-bone structure was proposed for integration into a bioanalytical system.
