Blasius equation.
Can anyone kindly tell me how to use Finitediffence method to solve Blasius's equation of laminar boundary layer (2f''' + ff'' = 0). I have consulted many textbooks but the numerical method is not used to solve the equation. I needed any online text or idea to quickly fix this.
Thanks, Lawal 
Re: Blasius equation.
Your equation looks wired to me, usually, Blasius's equation has f' term. By the way, what is your boundary conditions?

Sorry for the confusion,
2f''' + ff'' = 0 You can set z = 0.5 f y y = f'' x = f' and use, for example, RungeKutta method for the time or space marching. 
Re: Blasius equation.
The standard way to solve this equation is to use central differences to obtain a nonlinear set of equations which you can solve using Newton iteration.
An alternative is to use a RungeKutta and the "shooting" method, Tom.

See White "Viscous Flow" for a rather complete description and a code (RungeKutta)

I would be grateful if you could help solve this Blasius equation using shooting method for me f"' + ff" = 0, f(0) = 0, f'(0) = 0, f"(0) =0.4696 Thank You

Re: Blasius equation.
White's book has both the code needed and the RK subroutine. I have done this long time ago myself, don't have the book or my own notes handy, and don't have enough time to start working on this now.
If you can find White's book, and still have some questions or run into problems, I may be able to provide some help at that point.  Jarmo
