open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,
I want to model driftwood movement towards a hydropower intake in a river. As I am new to Telemac 3D i need to know if this can be done.

Pressurized flow?
The river in front of the intake must be modelled as free surface flow, but I also need to model the shape of intake and a part of the tunnel after the intake. The intake is well below the free surface.

Can Telemac handle the combination of free surface and pressurized flow, including intake shape, gate, tunnel? (I dont think that just putting in a sink without modelling the shape of the intake is good.)

Driftwood
I want to model movement of driftwood, typically floating trees (shape must be simplified). Can this be done in Telemac?

(In addition i am really confused about the connection between Telemac - Salome CFD - Salome Hydro - but that is probably a different topic.)

Hello,

TELEMAC-2D and TELEMAC-3D are implemented to model free surface flows.
Anyway, some hydraulic works can be modelled in TELEMAC-3D if you are not interested in the flow locally to these structures (e.g. culverts).
You can find a modelling of flows under ships (pressure field), e.g. in:
eprints.hrwallingford.com/1380/1/HRPP797.pdf
But it is not the usual use.

You have a few features available to track particle movements. Have a look at the drogues feature + keyword STOCHASTIC DIFFUSION MODEL if needed in the TELEMAC-3D manuals (user, reference).

Hope this helps,

PS : SALOME HYDRO is a module from SALOME to generate mesh e.g. and other features connected to TELEMAC.

SALOME CFD is the .module of SALOME connected to Code_Saturne CFD software. No direct link with TELEMAC, except SALOME can be derivated with special features.

Hi,

There is a very useful tool T2D-TRS (github.com/NHanousek/T2D-TRS/tree/main), designed to simulate tidal range schemes. It could also be applied to hydroelectric dams. However, this uses culverts and will not take into account the shape of the inlet.
