The objective of ‘
Fluid Mechanics of Microsystem’

course is two
-
fold
as the understanding of fluid with complex structure and fluid flow in micro
channels becomes important in the field of biot
echnology and
nanotechnology.


First objective is to understand the basic principles in the physical
phenomena of fluid mechanics found in most processes in chemical
engineering, biotechnology and nanotechnology. Second objective is to
strengthen the skill
s to apply these principles to the analysis, optimization
and design of real processes.

In this course, we introduce the basic concept of continuum mechanics,
conservation equation and Newton’s constitutive equation. Then, we deal
with the analysis of Navi
er
-
Stokes equations, dimensional analysis, creeping
flow, bounda
ry layer theory, turbulent flow
,
macroscopic balances

and
electrokinetic phenomena.
