open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

What kind of pollution can I simulate with TELEMAC??? 2d or 3d.

(thermic and salinity, what else???

thank you in advance.

Hello,

Well basically you can do any passive tracer, and you can add decay laws, or even source terms that would link tracers, or use Delwaq as a post-processing tool for water quality. Salinity and thermal studies are preferably done in 3D to take into account the buoyancy effects.

Hello JM,

I 3D modeled few weeks ago a chlorination tank using ANSYS FLUENT where I described the decay of Chlorine using a C code. Is it possible to do the same using TELEMAC2D/3D and how can I define the decay function?

Thank you,
Aissa

Hello,

This can be modelled with the source terms, you can look at what is done in subroutine difsou.f, there is an example and also a pre-progralled law, corresponding to LOITRAC=1.

With best regards,

Hi JM,

Can you please send me the name of the example?

Thank you for your help,
Aissa

Hi Aissa

have a look in the example 034_tracer_decrease

Regards

Thank you Chris. However I noticed that this example don't make use of subroutine difsou.f.

Yes but it use the default version of this subroutine where the type of law (=1) has been implemented.
As I know, the chlorine decay is a complex process.
So you should first fix the law of decay and then use this subroutine to program this law (eventually you need to add some other parameters...)

Hope this helps
