Example of turbulent flat plate:
we treat here an example of turbulent flat plate. the geometry and the
mesh already exist( 2D with 55x81 nodes). The flat plate have a lenght
of 0.4m.The intel velocity is supposed unifor and Re = 3.10 e 6.
1) Grid :
To visualize the mesh, face points and face grids we used scope of visualization.
In the fine window Flow solver provids to start iterations,
we can visualize residuals by the comand : convergence history.
the calcul is steady 2D ,with a CFL=0.5 and raug kutta explicit temporal discretisation. v_intel=120 m/s.The fluid used is AIR supposed perfect gas.
The results was visualized with CFView .
velocity vector :
if we zoom on the graph (x=0.2 m):
