Goals:
After this class you should be able to:
- Render the equations of motion dimensionless.
- Apply the law of dynamic similarity to develop scale models.
Reading
- The class notes.
- WWWR, chapter 9; BS&L, chapter 3
- Multi-Media Fluid Mechanics: Work through Dynamics:Reynolds Number: Low Reynolds Number Flow.
G.I. Taylor's demonstration of kinematic reversibility was taken from a famous film he made in the 60's.
Additional Readings:
Sir Geoffrey Ingram Taylor is generally regarded as the preeminent fluid
dynamicist of the 20th century. His genius was to combine detailed mathematical
treatment of complex phenomena with simple, precise experimental results. In class we
demonstrated one of the many phenomena associated with his name - the
Taylor-Couette instability. For a discussion of this and other phenomena associated
with G. I. Taylor, go here.
The reference to Taylor-Couette flow is about half-way down the page. A brief
biographical sketch of G.I. Taylor is given
here.
Demonstration:
Bernoulli's Equation. OK, it was supposed to be Taylor vortices, but there were
technical problems... We'll try that one next Thursday.
