F.M. White, Viscous Fluid Flow, Third Edition, McGraw-Hill, New York, 2006


To introduce concepts and analytical techniques for inviscid flows and laminar boundary layers and to teach when inviscid and boundary layer techniques may be used as simplified flow models to more complex problems. To introduce phenomena of turbulent flow, separation, drag and lift. Several homework problems are assigned throughout the course. Emphasis is placed upon good solution techniques and presentations.


After completion of this course, the students should be able to:

  1. Derive partial differential equations of continuity, momentum, and energy for compressible and incompressible flows[a]
  2. Apply control volume theory for solution of inviscid and viscous flows [a]
  3. Solve partial differential equations of selected external and internal flow problems [a, e]
  4. Compare and use different levels of flow approximations use simplified models when necessary [a,e]
  5. Solve external and internal flow problems [a,e]
  6. Solve boundary layer, laminar, and turbulent flow problems [a,e]
  7. Solve similarity transformation equations numerically using Runge-Kutta methods [a,k]
  8. Compute lift, drag, and separation for viscous flows[a,e]
  9. Make use of numerical and/or empirical methods when analytical methods fail [a,k]
