Hi, the governing equations for...

Hi,

the governing equations for rhoPimpleFoam are the continuity, momentum and energy equation of a compressible fluid. You can refer to Ferziger and Peric and Hirsch books, for example.

For...

This should not be too difficult: you can simply create an interface between the two codes. If you want to do things more cleanly, you probably should take a look at the Lagrangian solver already...

I do not know enough about your solver to comment on this. Is your solver written in OpenFOAM? What kind of coupling do you need?

You have to replace the k-epsilon implementation with the RSTM implementation for multiphase flows. The code does not rely on the turbulence models in the library, since you have to include the...

Hi Gerhard,

if with LES you mean a Smagorinsky-type model for the continuous phase, the implementation is easy, and can be based on what is already available into OpenFOAM.

Hi,

the solution algorithm should not have extreme difficulties to deal with non-Newtonian problems.

In OpenFOAM 2.0.0 twoPhaseEulerFoam implements the PIMPLE algorithm, which makes it more...

How dense (average volume fraction)?



Yes, it can be added very easily re-using the work done for single-phase flows by OpenFOAM developers.

Hi Peter,

the main problem is that the code is outdated. I have written it using OF 1.3/1.4, and I did not adapt it to the new versions of OpenFOAM(r).

However if you drop me an email I can...

Hello,

no problem. I simply wanted to clarify the code is not published. The reasons are many:

a) it is not up to date
b) some parts are not tested (see interstitial fluid effects, for...

Just to clarify, that code is NOT released publicly, so I would like to know who is using it.

Check you email. :-)

About your address, I have no idea. Also mine should be visible, and it should be possible to download a vCard, but the forum is so bloated I didn't find it anywhere! :-P

Hi Raghavendr,

I have no problem to share the code, but I don't really know how useful it can be for your purposes, because starting from the single-phase LES classes in OpenFOAM and adapting them...

Hi,

yes, I worked on that during my PhD. I essentially used Smagorynsky type models for the gas phase to simulated gas-particle flows. The work was done with OF 1.4.0, and does not compile with...
