Electrokinetic particle transport in micro nanofluidics : direct numerical simulation analysis This text which was developed in part from some of the authors most recent journal papers includes a brief introduction of micro nano fluidics and a mini review of the basic theories of DC electrokinetics. It may serve as a useful reference for researchers and graduate students in the micro nano fluidics community who might have limited experience and or time in developing their own DNS codes to explore the active growing and interdisciplinary field of research. Readers could modify and extend the mathematical models COMSOL files and MATLAB codes in this book for their own research
