Module 4: Vorticity Stream Function Approach for Solving Flow Problems
  Lecture 24:
 

Now for equation (24.7) we can write

 

(24.9)

 

If we put we shall obtain

 

           (24.10)

And we rewrite equation (24.4) as

  (24.11)

  (24.12)

Thus we have now a system of simultaneous equation, (24.8), (24.10), (24.11) and (24.12) to be solved for and
