Match each analysis method in List I with what characterises it in List II.

List I

A. Blasius solution

B. Falkner-Skan family

C. Momentum integral equation

D. Pohlhausen method

List II

1. Similarity solutions for wedge flows with a pressure gradient

2. The exact laminar flat-plate case with no pressure gradient

3. Closes the integral equation with an assumed quartic profile

4. Relates momentum thickness growth to wall shear and pressure gradient

Select the correct match.

  • A.A-2, B-1, C-4, D-3
  • B.A-1, B-2, C-4, D-3
  • C.A-2, B-4, C-1, D-3
  • D.A-3, B-1, C-4, D-2

Answer: A

The four form a natural progression from an exact special case, through a family of exact solutions, to an integral formulation and finally a practical way of closing it. Each buys generality at the cost of some exactness.
