Announcement A short Term Course On Micro Scale Engineering January 03 – 08, 2011

Course Content
A short Term Course (under QIP)
January 03 – 08, 2011

Title: Micro Scale Engineering

In recent years, many prototype devices of Micro-Electro-Mechanical-Systems i.e. micro sensors, micro actuators,
micro mixers, micro pumps, micro valves etc. have been developed. The optimization in performance of these
devices requires understanding of fundamental concepts i.e. breakdown of constitutive laws and new flow regimes
etc. Many fundamental issues that are not observed in macro flows are prominent in micro scale fluid dynamics.
The Reynolds number is much less than unity due to small transverse length scales. However, the velocity
gradient is quite high leading to high viscous forces. Thus, the hydrodynamic pressure drops in a single fluidic
network is quite high and the design of micro pump is no more trivial. Therefore, electrokinetic and surface
tension forces are used as alternatives to move the bulk fluid. The high viscous damping affects the probability of
hydrodynamic instabilities, essential for effective mixing. Thus, concept at chaotic mixing as an alternative
strategy in an active field of research. In biological applications, molecular structural changes electrical charges,
and polar structures are frequently encountered leading to different mechanics in micro scale. Overall, there are
fundamental difference in micro flows from macro flows in the following areas:
• Surface dominated effects
• Low Reynolds number effects
• Non-continuum effects
• Multi scale effects
This course is directed to the researchers in multi disciplinary areas i.e. Civil Engg. Chemical Engg. Biotechnology,
Aerospace Engg and Mechanical Engg. Fabrication of micro devices, associated theoretical concepts
and characterization tools will be discussed.
