Default RNG k-epsilon model

I have some problems to interpret some results of turbulent simulations with the rng-kepsilon model. I am using a turbulence model to solve the influence of the walls (in Fluent this is called Two Layer Zonal Model) which deals with a one equation turbulence model of Wolfstein. ANyway my problem is that I have a huge over-prediction of pressure drop for my flow (water, incompressible, steady state assumed, no heat transfer) through a welleded geometry. The only explanation I have is that there are some laminar parts in my flow which make the solution with the RNG-kepsilon model inaccurate??

ANy ideas

Thanks in advance

Phil

(1). The description is too vague for me to know what you are doing. (2). If you can't explain the problem clearly, you are likely a new user or newcomer to CFD. (3). If you are using Fluent, you can post the message at the Fluent forum, where the code experts can have a chance to answer it.
