MEC4425 - Micro/nano solid and fluid mechanics

6 points, SCA Band 2, 0.125 EFTSL

Undergraduate Faculty of Engineering

Leader: L Yeo and J Friend


Clayton First semester 2007 (Day)


Introducing micro- and nano-technology in the design of next-generation electronic and energy systems and biomedical devices. Basic concepts and physics of micro\nano-systems, including continuum and molecular theories, Low Reynolds number flows, capillary effects and interfacial flows. Flows in channels of arbitrary dimensions, convective-diffusive mass transport, electro hydrodynamics including classical double layer theory, electrophoresis, electroosmosis, dielectric polarisation and dielectrophoresis are discussed. Active materials, scaling issues, contact mechanics and the design of micro/nano-fluidic devices. Modelling and analysis of systems using Matlab and Mathematica.


To instill

  1. exposure to the emerging fields of micro and nano technology, particularly for biomedical engineering
  2. thorough understanding of the physical behaviour of solids and fluids at the micron and nanometer length scales through continuum and molecular theories
  3. an understanding of the difficulties in fabrication, manipulation, and imaging of components at the micro scale and beyond
  4. an appreciation of the various fluid transport mechanisms in micro/nano channels or devices and physical interaction mechanisms in solids at the micro/nano scale
  5. knowledge in the design of micro/nano-electro-mechanical-systems and micro/nano-fluidic devices for various bio-applications

To develop the ability to
  1. construct models of micro/nano components and systems
  2. solve the fundamental equations of motion governing the dynamics of such systems analytically, semi-analytically or using numerical techniques to understand their behaviour for prediction and design
  3. apply the knowledge provided in the course for the design of practical micro/nano devices
  4. know where and how to continue learning on advanced and/or new topics in micro/nano solid and fluid mechanics.
