Orr Sommerfeld equation
Hi, I am working on my thesis "laminar flow control in airfoil flow". I want to solve the OrrSommerfeld equation. I wrote a FORTRAN code for solving OrrSommerfeld equation in Blasius boundary layer, but it doesn't work properly. If anyone has got a similar code, I would be greatly thankful to receive it via email. And how I can develop that Blasius code for airfoil flow? Thanks.

Re: Orr Sommerfeld equation
See the book
Schmidt and Henningson Stability and transition in shear flows They have some matlab codes. They will help you to get started but it is not for an airfoil. You can get the code from the website of Schmidt also. 
Re: Orr Sommerfeld equation
It doesn't have the codes but you could look at
"Absolute and convective instabilities in separation bubbles. Aeronautical Journal, December 1995" by Allen & Riley. They study the OrrSommerfeld equation for flow over and aerofoil.
