Dear Stanislaw,

 

(Oops, sorry incomplete message sent by error!)

 

        I was thinking of experimenting it by defining a narrow band of quads, assigning them to a composite to define a boundary and using it as an inlet, with a time dependent velocity profile,

       But if I intend to mimic the fluid blowing inside the channel it would require adding "fluid flux" through the active cells not only imposing, say, a normal fluid velocity over the blowing strip ie. ideally "injecting fluid" via a velocity inlet type Boundary condition,

I hope you get a sense of the subtlety I hardly am trying to detail here. ideally fluid injection-mass flux Vs. imposed velocity profile at the wall strip

 

      Any comment or suggestion on the above aspect ?

 

Thanks in advance,

 

with gratitude,

 

Saad

Dear Saad,

You could experiment with the boundary conditions and applying it either from file or as an equation. If your case is fully 3D (not homogeneous expansion) you could design the mesh to have the ability to set required conditions only to the regions you choose.

Cheers,

Stan

Dear all,

 

           I use Nektar++ mainly to study time dependent 3D plane Poiseuille flow, using  the Incompressible Navier-Stokes Solver (using a fully 3D configuration),

I'm wondering what would be the best approach to add Blowin and/or Suction at the wall ?

Looking into the user-guide version 5.1.0 section 3.5.1- XML-Session-File>Forcing>Absorption seems to be a usable feature in this context

Is there an efficient and suitable approach to add these perturbations to the flow ?

 

           Any general guidelines to achieve this are really appreciated,

 

Thanks in advance,

 

Kind regards,

 

Saad
