5 5/19 Niche for Chemical Engineers in 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 6/19 Examples Drug delivery patches Flow around and into cancerous tumors Heart - Lung Machine High density integrated circuit chips

7 7/19 Brain Cancer implantable “patch”

8 8/19 Transdermal glucose monitor

9 9/19 Heart-Lung Machine

10 10/ Gallon reactor- on its side!

11 11/19 SHANGHAI OIL REFINERY

12 12/19 Dramatic picture of a refinery

13 13/19 Large distillation tower

14 14/19 Chemical Process equipment Catalytic cracking unit From Chemical Engineering Education,2000

15 15/19 Structure of flowing fluids Gas-liquid flow in a pipe Movies from NASA- Lewis, see mjm homepage for more info

16 16/19 Structure of flowing fluids Gas-liquid flow in a pipe

17 17/19 Structure of flowing fluids Gas-liquid flow in a pipe

18 18/19 Structure of flowing fluids Gas-liquid flow in a pipe

19 19/19 Structure of flowing fluids Interfacial waves generated by a shearing gas flow W.C. Kuru mjm Research group

20 20/19 Interesting fluid flow phenomena Bands of different size particles forming in a rotating tube Physics Fluids 2000, et al. and Acrivos

21 21/19 Interesting fluid flow phenomena Kelvin-Helmholtz Instability (A jet flowing into a stationary fluid) Next few movies from:

22 22/19 Interesting fluid flow phenomena Rayleigh-Benard instability Top wall is cooled causing fluid flow

23 23/19 Interesting fluid flow phenomena A buoyant jet

24 24/19 Interesting fluid flow phenomena Rayleigh -Taylor Instability Hot fluid below cool fluid

25 25/19 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

26 26/19 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 27/19 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) "

28 28/19 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 29/19 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
