B6a: Viscous Flow

Trinity revisions 12-13: Week 1

  • Week 1: Problem sets 1-2 and solutions
    • 80 minutes/5 questions = 16 minutes per question

Typo on Q5: Ansatz should be $e^{i\Omega t}$ (missing $i$).

By request, here is a simple explanation of how to prove the Cauchy stress theorem.

Trinity revisions 12-13: Week 2

  • Week 2: Problem sets 3-4 and solutions
    • 80 minutes/5 questions = 16 minutes per question

Typos and additions (Fri. May 3): For Q2, you can ignore body forces. For Q3, the solution in part d should have \[ -F_1 = -\mu \frac{U}{L} \left( \sqrt{\text{Re}} \pd{u}{Y} + \frac{1}{\sqrt{\text{Re}}}\pd{v}{x}\right) \]

(Note the Reynolds number factors are slightly changed)

  • Week 3: Problem sets 3-4 and solutions
    • 100 minutes/4 questions = 25 minutes per question
  • Week 4
  • Week 5

Older material (2009-2010)

During the 2009-2010 Trinity term, Oxford students made a valiant attempt to complete every single question of the last twenty years of B6a exams. Each filled square corresponds to a student successfully answering one of the problems.

Note: The material below was prepared prior to the 2009-2010 year. It has not been updated since then.
