Hello.
as the title states I'm on the hunt for the reference for oneEqEddy and dynOneEqEddy used in OpenFOAM 1.7.1
I look inthe soure code but thet didn't stated any ref there.

Thanks

Well I was also looking for a reference and I found this paper. I haven't read it yet, but this might be the reference you are looking for.

regards,
Awais

oneEqEddy is defined by:

k-Equation:
Yoshizawa, Akira; Horiuti, Kiyosi -- A Statistically-Derived Subgrid-Scale Kinetic Energy Model for the Large-Eddy Simulation of Turbulent Flows -- Journal of the Physical Society of Japan -- 1985 -- Vol. 54 -- Issue 8 -- pages 2834-2839 -- doi: 10.1143/JPSJ.54.2834 p, li

k_sgs-transport:
Menon, S; Yeung, P.-K.; Kim, W.-W. -- Effect of subgrid models on the computed interscale energy transfer in isotropic turbulence -- Computers & Fluids -- 1996 -- Volume 25 -- Issue 2 -- pages: 165-180 -- doi: 10.1016/0045-7930(95)00036-4

where the parameter c_k = 0.0094 is defined like in oneEqEddy by:
Nakayama, A.; Vengadesan, S. N. -- On the influence of numerical schemes and subgrid-stress models on large eddy simulation of turbulent flow past a square cylinder -- International Journal for Numerical Methods of Fluids -- 2002 -- Volume 38 -- Issue 3 -- pages: 227-253 -- doi: 10.1002/fld.214

thanks for this important information.
But I couldnīt find the k-equation from the oneEqEddy-equation in the paper of Yoshizawa


I am looking for this equation (see attached picture), which is defined in oneEqEddz.C (OpenFOAM-2.1.1\src\turbulenceModels\incompressible\LES\oneE qEddy\oneEqEddy.C) and the used constant ce_ = 1.048 (defined in: Z:\OpenFOAM\OpenFOAM-2.1.1\src\turbulenceModels\incompressible\LES\GenE ddyVisc\GenEddyVisc.C)

Could anyone help me please?

Thanks a lot
