Hi Mohammed,

Can you give a decription to your problem. For some reason I can only see the title (Fluid Flow).

Thanks

Have you done the courses in the Learning section on here?

Look at the turbulence question in another way. Why wouldn't you set a turbulence model given you need to decide what you need in your model. 

[Rob]

There's a theory that if the mesh is fine enough, and the time step small enough that a laminar flow will pick up the turbulent eddies as part of the result. Given the mesh cell count would be near infinity and the run duration would be rather long I'm not sure we'll ever find out. 

Being slightly more realistic, the result would probably not converge well, and may not be overly accurate. Try running laminar and then turbulent and compare the results.
