  2. About the Course • Learn basic phenomenon and mechanism in fluid dynamics. • Understand and master some important theories and equations • Suggestions and Tips • DO practice all the homework assignments • ASK or DISCUSS with professor or TA whenever you have questions

  3. Tutorial Proposed Context: 1. Concepts Review 2. Example Demonstration (examples including homework problems) 3. Exam Preparation Marking Scheme: Class participation: 5% Assignments: 15% Mid-Term Exam: 20% Final Exam: 60% Reference Book: D. J. Acheson, Elementary Fluid Dynamics, Clarendon Press, Oxford, 1990 TA357 .A276 1990 G. K. Batchelor, An Introduction to Fluid Dynamics, Cambridge University Press, 2000 QA911 .B33 2000   

  4. Fluid Mechanism @ HKUST Expertise: Dr. Jimmy C H FUNG (MATH) Dr. Jian Ping GAN (MATH) Prof. Mohamed S GHIDAOUI (CIVL) Prof. Chin Tsau HSU (MECH) Dr. See Chun KOT (MECH) Prof. Kenny Chung Sau KWOK (CIVL) Dr. Alexis K H LAU (AMCE) Dr. Huihe QIU (MECH) Prof. Ping SHENG (PHYS) Dr. Wing Yim TAM (PHYS) Prof. Penger TONG (PHYS) Prof. Weijia WEN (PHYS) Prof. Kun XU (MATH) Department of Civil Engineering

  5. Masters of Fluid Mechanism Sir Isaac Newton (1643-1727) Daniel Bernoulli (1700-1782) Leonhard Euler (1707-1783) Joseph Louis Lagrange (1736-1813) Sir George Gabriel Stokes (1819-1903) Theodore von Karman (1881-1963) Osborne Reynolds (1842-1912) Ludwig Prandtl (1875-1953)

  6. The Beauty of Fluid Mechanism

  7. Tools to explain Fluid Phenomena

  8. Lecture Notes Learn form others http://www.maths.qmul.ac.uk/ http://ocw.mit.edu/OcwWeb/ Programs/ Software/ Tools http://www.acricfd.com/ Videos http://web.mit.edu/fluids/www/Shapiro/ncfmf.html Media Resources

  9. Institute for the Environment (IENV) Air Quality Modeling Group @ HKUST Leaded by: Dr. Jimmy C H FUNG & Dr. Alexis K H LAU Atmospheric & Environmental Database http://envf.ust.hk/dataview/gts/current/

  10. Met model Predicted Quantity: e.g., ozone AQ violation Air Quality Modeling Chemical, Aerosol, Removal modules CTM Observations Emissions

  11. Simulation Observation Surface Wind Validation

  12. Land-sea breeze circulation cells in PRD

  13. Ozone Concentration Modeling in PRD region

  14. Simulation Performance: How about the background’s contribution? Ozone

  15. Contours show the Concentration of ozone from ozone chemical model calculation Ozone chemistry is non-linear Decreasing NOx decreases Ozone (1011 molecules cm-2s-1) NOx-limited regime Decreasing VOC decreases Ozone VOC-limited regime VOC emissions Decreasing NOx increases Ozone NOx emissions (1011 molecules cm-2s-1)
