Niche for Chemical Engineersin Fluid Mechanics

• Hard problems involved detailed phenomena that
  act on a small scale but influence the large
  scale
• Also systems with mass transfer and/or chemical
  reaction occurring

6
Examples

• Drug delivery patches
• Flow around and into cancerous tumors
• Heart - Lung Machine
• High density integrated circuit chips

Favorite quotes

• Sufficiently advanced technology is
  indistinguishable from magic
• An engineer can always befuddle a financial
  person with technology, but a financial person
  can never over whelm an engineer with numbers

Favorite quotes

• The more you know, the better engineer you will
  be!
• I knew then as I can confirm now, nothing would
  ever be as hard to understand as transport
  phenomena and the Navier-Stokes equations. I was
  never again intimidated by quantitative problems
  and I appreciated the need to formulate simpler
  problems that gave useful results.

27
Favorite quotes

• The history of modern science has shown
  repeatedly that a
• quantitative description of nature can often be
  achieved most
• successfully by first idealizing natural
  phenomena, i.e. by
• setting up a simplified model, either physical or
  mathematical,
• which crudely describes the essential behavior
  while neglecting
• details.
• (In fact, one of the outstanding characteristics
  of great
• contributors to modern science has been their
  ability to
• distinguish between what is essential from what
  is incidental) ........"

Who said them

• A top design engineer from DuPont
• A CEO of a steel company
• One of the most influential chemical engineering
  professors of all time
• A top research/technology engineer from Shell
• An ND Cheg Alum who is a VP for General Mills

29
Conclusions

• Fluid mechanics is fun!
• The niche for chemical engineers is understanding
  the effects of small scale phenomena that cause
  large scale outcomes
• This course possesses great depth and should be
  useful to your educational development even if
  you do not use it day to for a living
