Microfluidic flow simulation: Stacking one-dimensional study

This study deals with the analyte stacking one dimensional numerical approach which results are closed to the experimental data. The first section is a general presentation of this phenomenon and the multidimensional equations involved in the model. This model is made of a set of electro-diffusional coupled transport equations. In the second part the one-dimensional equations and the numerical methods used for their resolution are exposed. In the third section the time resolution algorithm is given and to increase the time precision order we propose a fixed point algorithm. The fourth and last part is dedicated to the numerical and the experimental results.
