test prob for 2D unsteady navier stokes equation
 
hi friends

I am looking for test problems for my 2d unsteady Incompressible Navier Stokes equations flow solver .

plz help/ suggest

thanks

Dear Shah,

I would suggest that you start off with the laminar vortec shedding past cylinder. This problem is very well documented and can therefore be easily validated. Other problems include airfoils at higher angles of attack and flows past bicircular airfoils.

Hope this helps

Regards,

Ganesh

You can tke flow across stationary circular cylinder for Re>60 sachin

I will try to post some results by the end of the week including comparisons. The basic data product is the recirculation length behind the obstacle as a function of the evolving simulation time.
