Results for case Channel Flow

Code: Code_Saturne, v1.3.2

Version:

Authors: Juan Uribe

Method and Numerical Options

Models

Mesh

1D mesh. 100 volumes, clustered near the wall. Min y+ = 0.5

• channel100x1y+1_h1.unv: Mesh for the channel

Description of the results files

ASCII format. For each model there is a file, named res_plus_XXX.dat where XXX is the model descriptor.

The columns are organised as:
For the Phi-f model:

# y+ U+ k+ Eps+ v2+ Phi Nut+ F+

For the SST model:

# y+ U+ k+ Omega+

For the EBM:

# y+ U+ uu+ vv+ ww+ uv+ uw+ vw+ esp+ alpha

• res_plus_EBM.dat: Elliptic Blending model

• res_plus_PHI_F.dat: Phi f model

• res_plus_SST.dat: SST model

Boundary conditions

1D mesh, periodic in the streamwise direction. Pressure gradient imposed to obtain friction velocity U_t = 1. Zero velocity at the wall. All other boundaries have symmetry boundary conditions.

Aditional information:

To run the case just copy the FORTRAN files and modify the lance script accordingly:

• fotrans_v1.3.2.tar: Fortrans and lance script used (v1.3.2)

Velocity profiles	Kinetic energy profiles
Dissipation	Eddy viscosity
