Course content

MEMS: applications and relevance within microfluidics.– Microhydrodynamics: continuum hypothesis, flow regimes in microscale, governing equations, boundary conditions, analytical solutions; surface, interface and body forces relevant in the microscale; pressure drop. Electrokinetics. Basics of acoustofluidics. Wetting and contact angle dynamics.– Two-phase flow and heat transfer in microchannels. Heat and mass transfer of droplets and bubbles at the nano- and micro-scale. Examples of applications related to high heat fluxes system (cooling of electronics), condensation and phase separation in micro-channels. Overview of experimental methods applied to microflows (micro-PIV, flow visualization) and micro/nano fabrication techniques. Characterisation of the surfaces at the nano-, micro-scale. Overview of numerical techniques for the simulation of micro flows. The course is given next time AUTUMN 2021

Learning outcome

The course is intended to give an insight into the physics involved in fluid flow in microchannels, including different micro flow devices and their applications. After completion of this course, the student will have:

- knowledge on: general properties of MEMS, physics involved in gas and liquid flow in microchannels, surface forces dominating in the microscale, two-phase flow in microchannels, heat transfer in microchannels in the presence of boiling and condensation, bubbles and droplets manipulation in microfluidic applications.

- an overview on: experimental techniques and simulation approaches used in microfluidics;

- skills on: solving simple problems of gas and liquid flows in microchannels, designing a microchannel system, evaluation of the appropriate experimental technique for the study of a given flow problem.
