OVERVIEW: KUTTA CONDITION

OVERVIEW KUTTA CONDITION

• Suppose we model the flow around an airfoil using
  a potential flow approach
• How many theoretical potential flow solutions are
  exist?
• The answer is that there are infinitely many.
• Flow (1) and Flow (2) satisfy all conditions for
  potential flow theory, however G1 ? G2, so we
  know that L1 ? L2 (recall rotating cylinder
  example)
• Experimental evidence (nature) tells us which G
  should be used ? Kutta Condition (see 4.5)
