what is new in twoPhaseEulerFoam in OP3.0.1

sinatahmooresi · May 11, 2016, 06:41

Hi friends!
I started to use OP3.0.1 recently and I got confused in many changes of twoPhaseEulerFoam ! is there any body to help me to find some description about this solver and it's changes in new version?
good luck friends

I believe the best way to understand this is to compare tutorials. Did you try to check in the tutorials what are the differences? What don't you understand?

hi friend and thanks for your guidances.
for example : directories like alphat , km , epsilonm

Hi,

In the latest twoPhaseEulerFoam, it can deal with:

1. compressible flow;
2. the governing equations are conservative form;
3. add a switch to solve p_rgh for highly non-orthogonal mesh;
4. LES is implemented;
5. mixture k-Epsilon and other RANS turbulent models were implemented;
6. turbulent swarm and turbulent dissipation force were added;
7. wall functions were enhanced;
8. LTS was supported (in reactingTwoPhaseEulerFOam);
9. others?

Best,

alphat is the turbulent thermal diffusivity
km, and epsilonm are the k, and epsilon values when you use the mixtureKEpsilon model.

No problem. Just to let you know you can "Like" a post if it was useful to you.

Hi

I want to simulate bubblyflow
which one should I use,twophaseEulerFoam or ReactingtwophaseEulerFoam?
What is different between them?

Hi masoudsh!
i guess twoPahseEulerFoam is better than another one, did u checked tutorial of bubble columns of twoPhaseEulerFoam yet? i guess it could be helpful
Regards
