I have been doing a simulation of Blasius equation:(adsbygoogle = window.adsbygoogle || []).push({});

F'''+FF''/2=0 with F(eta) where eta is a similarity variable

eta=(y-1)/(x^(1/2))

F'(0)=1 u(y=1,x<<1)=1

F(0)=0 v(y=1,x<<1)=0

F'(infinite)=0 u(y=infinite, x<<1)=0

You can observe that the BC's are different of the flow over flat plate. This is obtained for a mixing thickness in the near field of a two-dimensional jet, near the orifice of exhaust (are you agree?).

in this page:

http://www.rit.edu/~pnveme/Matlab_Course/Matlab_App_ODE.html [Broken]

where shooting method is employed in Matlab, it is said numerical methods (Runge Kutta, or the internal Matlab function ODE45) have normalized value F'(infinity)=1.

I have programmed it in Matlab but now I don't know how consider the value 0 at infinity instead of 1.

Could you help me?.

Thanks.
