Hi
Can anyone help me in telling me how can i set up a eulerian lagrangian model in fluent.
Thanks in advance

You have to use Discrete phase models available in Fluent . The continuous phase is solved like an continuum and the secondary phase/discrete phase is solved through lagrangian method.

Kindly tell me the steps to put a eulerian langrangian model in fluent.
I am not been able to interlink the secondary phase of the DPM model with the secondary phase of the eulerian model
kindly tell me how to do that
Thanks

Hi,

After loading the mesh file, go to the models. Select your turbulence model then select Discrete Phase. If you want the particles to exchange momentum with the continuous plahse than select the option "interaction with continuous phase". Now click the injections button. Then click create button. Add your particle properties and the way particles are injected. You may have these via spray cone, single stream etc...
Specify the position of injector (x, y and z) in the same window. Also specify the number of particle streams.

That should be it.

You can specify the physical properties of the injected particles in the Materials menu.

Hello
Thanks for the reply
I have one clarification. While using the Eulerian-Langrangian Model is it so that we have to on the eulerian model from define>model>multiphase>eulerian and then on the dpm model as discussed above
or

Dpm itself takes care of the eulerian and Lagrangian framework of the calculation.

and
Is that possible to use both eulerian and dpm model at the same time in fluent if yes how??

Thanks

You dont have to select multiphase if you are tracking the particles using Lagrangian approach. You will need it if you want the second phase to be solved using eulerian approach.

I dont know whether you can use both multiphase eulerian and DPM at the same time.

hi mali

is discrete phase (particles), turbulence always?
