Presentation Transcript

  1. Advanced Fluid Mechanics • One of the required courses for the graduate students in our department • The official language is English • Learning the technical words • Textbook reading skill • Technical writing skill

  2. Course introduction • Goal: To study theories of fluid mechanics and to analyze and solve the fluid systems. • Pre-requisite : Transport Phenomena and Unit operations (I) 

  3. Outline 1. Introduction and overview2. Non-Newtonia fluids3. Eequation of changes for isothermal systems4. Velocity distributions with multi-variables5. Viscous flows6. Irrotational and porous medium flows7. Boundary-layer flows8. Introduction to computational fluid dynamics

  4. Textbooks 1. R. B. Bird, W. E. Stewart, and E. N. Lightfoot , “Transport phenomena”, Wiley 2. James Wilkes, “Fluid mechanics for Chemical Engineers”, Prentice Hall, 1999 3. James Welty et al. (3W+R), "Fundamentals of Momentum, Heat, and Mass Transport", 4th ed. (Wiley). 4.游文卿,"化工輸送現象-動量篇", 台灣區域發展研究院,1993 

  5. Syllabus • Week 1~8 Introduction, Non-Newtonia fluids, Equations of change, viscous flows • Week 9 Mid-term exam Week 10~17 Velocity distributions with multi-variables, Irrotational and porous medium flows, Boundary-layer flows, Computational fluid dynamics • Week 18 Final exam

  6. Evaluation • Mid- 35% • Final 40% • Project 10% • Homework 15%

  7. Transport phenomena • Transport phenomena includes • Momentum transport • Heat transport • Mass transport

  8. Cases of fluid mechanics • an F-18 flying at a Mach number of 1.4 at 35,000 feet a T-38 flying at a Mach number of 1.1 at 13,700 feet http://www.galleryoffluidmechanics.com/shocks/ifs.htm

  9. VISCOUS BUCKLING OF A LIQUID COLUMN a viscous syrup as it "piles" up on a table. The term buckling comes from the upstream bending of the liquid column.

  10. Simulation of Microfluid Systems

  11. Fluid Mechanics • Static mechanics • Fluid mechanics

  12. Pressure variation in a static fluid P6 P3 y P2 P1 x z P4 P5

  13. A Static fluid case ΔFs y Θ ΔFx ΔS x Δy Δz Δx z ΔFy
