The aim of the course is to present classical and recent numerical and experimental methods for studying transport phenomena in micro- and nanofluidic devices. Special attention is given to numerical simulation techniques and experimental methods in relation to practical engineering problems.

In recent years the progress in miniaturization technology has opened up new pathways for fluid dynamics. Flow in micron and nanometer scale devices are distinct from macro scale flows due to the large surface to volume ratios and the coupling of flow with heat and mass transport as well as electromagnetic fields. In addition, fluids with nanoparticles, such as nanofluids, have flow and thermal properties that may differ greatly from the background solvent properties. Hence, engineering design for micro and nanofluidic devices is unique from the large scale and requires special attention to surface forces, local chemical conditions, and applied electromagnetic fields.

Transport phenomena in micro- and nanoscale are characterized by surface interaction (solid-fluid or fluid-fluid). Dominance of surface forces leads to unique flow phenomena such as electrokinetic flows, surface tension driven flows, and nanofluids.
As device length scales shrink the continuum description may fail and under some conditions. The course will present various simulation techniques for continuum, molecular and meso scales. Experimental methods will also be presented for characterization of devices and validation of numerical methods.

The lectures address fundamentals of flow in micro- and nanofluidic devices as well as modern simulation and experimental methods. The course is designed to assist engineers and scientists in the design of fluidic MEMS (microelectromechanical-systems) and NEMS (nano-electromechanical-systems).
These integrated systems are emerging in many commercial applications such as gene and proteome profiling, bio-chemical sensors, lab-on-chip, cell-on-chip devices and nano-medicine.

This course is addressed to advanced students and scientists from engineering and applied sciences, as well as to physicists and mathematicians interested in fundamentals in the field of micro- and nano-fluidics.
