Hello,

I would like to simulate an oil turbulent flow with a wall thermal transfer. So, I use a low-Reynolds turbulence model and my mesh is created to have Y+ equal to 1.

To simulate the thermal viscous layer, do I have to have a T+ value equal to 1?
In my case, the Prandtl number is equal to 60 ...

Hello

Sorry my late answer ! I have worked on Ubuntu in recent months.

I launch the code_saturne command in the case directory (See as an attachement).

Hello,

I had the same error but I re install the syrthes codes taking into account the Yvan post (Jeu Jan 07, 2016 9:53 am ):

To path files, I use the command:
find /home -type f -name "ecrire_fichier.c"

And the ...

Hello

I try to install Salome 7.6.0, Code Saturne 4.0.5 and Syrthes 4.3 via Oracle VM Virtual Box 5.1.0 on Ubuntu 16.04 LTS. So I have very carefully read your discussion.

The installation of Salome and CS is OK and I was able to launch the tutorial 1 (Simplified nuclear vessel with salome and ...

Hello,
I would like to use CS without graphic display to perform a parametric optimization with windows 7 64bits.

I try with the windows command prompt:
“code_saturne.exe run –param text.xml”
But there is an execution error

Thanks

Hello,

Thank you for your answer.

The low speed and the inlet pressure are known.
I want to evaluate the heat transfer, the outlet temperature and the outlet pressure (to obtain the pressure drop).

For the inlet, I will use the velocity and thermal dirichlet condition and, for the outlet, a ...

Hello,
I would like to evaluate the wall heat transfer for a low oil flow speed (0.001m/s) with a high pressure (15bar) in a thin pipe (diameter = 0.002m)
Code_Saturne can realize simulations with the following configuration:
- Pipe diameter = 2 mm
- Pipe length > 0.5 m
- Oil density = 885 kg/m3 ...

Thanks you for your answer

Another question: Salome can create a structured mesh and export this mesh ? The "hexahedron (i,j,k)" function can create a structured mesh but I don't export my mesh to visualize with paraview structured function (Extract subset function).
If the anwser is not, I will ...

Bonjour,

Le code saturne accepte les maillages structurés (plus difficile mais on peut le paramétrer) et non-structurés (utilisation de Salome).

Je voudrais savoir si cela est utile de réaliser un maillage structuré . Est ce que Saturne se sert du maillage structuré ou le transforme-t-il en un ...
