Questions and Answers

In potential flow of a fluid with a region of vorticity, what can be said about closed curves that enclose the vorticity?

  • Their circulation values depend on the fluid viscosity
  • They have the same value for circulation (correct)
  • They have different values for circulation based on their size
  • They do not have any circulation

    • What does the Kutta–Joukowski theorem in fluid dynamics state about the relationship between lift per unit span (L') and circulation (Γ)?

  • $L' = k ext{Γ}$, where k is a constant (correct)
  • $L' = rac{1}{ ext{Γ}}$
  • $L' = ext{Γ}^2$
  • $L' = rac{ ext{Γ}}{k}$, where k is a constant

    • What is the relationship between circulation and curl or vorticity according to Stokes' theorem?

  • The flux of curl or vorticity vectors through a surface S is unrelated to the circulation around its perimeter
  • The flux of curl or vorticity vectors through a surface S is equal to the double of the circulation around its perimeter
  • The flux of curl or vorticity vectors through a surface S is equal to the circulation around its perimeter (correct)
  • The flux of curl or vorticity vectors through a surface S is inversely proportional to the circulation around its perimeter
