Results for case 3D Diffuser

Code: Code Saturne

Version:

Authors: Juan Uribe, Flavien Billard

Method and Numerical Options

Models

Mesh

The mesh has 250x50x96 cells with refinement near the walls. The maximum y+ value of the first cell is less than 2. The domain extends up to 40 time the inlet height.

Description of the results files

The zip file contains all results for all models as submitted to the 13th ERCOFTAC/IAHR workshop. There are velocity profiles at locations and velocity contours. Also a pressure coefficient on the mid-spanwise location at the straight wall is included.

For a full description see here

Boundary conditions

Inlet profiles taken from a duct flow precursor simulation with the same mesh on the Y-Z planes. No interpolation required.

The walls have no-slip condition except when using the SSG model where a scalable wall function is used.
