Is it possible that the eulerian wall film affects the core fluid so I could get the lift and drag affected in the wet condition?

The film only effects the near wall cell, and is assumed to have no thickness as far as blockage is concerned. Have a look into the model theory & limitations: it's all explained in more detail.

what do you mean with only affects the near-wall cell? the wall cell?
What is blockage?
I got this limitations:
The following limitations exist for the Eulerian Wall Film model:
The Eulerian Wall Film model is available for 3D geometries only.
Many models (for example, VOF multiphase flow or radiation) will not interact correctly with the film model without first modifying the boundary conditions using UDFs.
Wallfilm behavior at junctions with baffles (zero-thickness walls) may lead to unphysical results due to the local mesh topology (wall, wall-shadow) and should be used with care, that is, isolated film walls must not share a common edge.
The wall film can only be single-component, but not multi-component.
The Eulerian Wall Film model is not compatible with non-conformal interfaces.
The Eulerian Wall Film model is not compatible with mesh operations in Fluent (such as mesh adaption, cell separation, face zone extrusion, and cell zone type change).
