hello guys


I want to make simualtion where i have air with sand particles on it



Do you have any idea about how to do that ?!!


Many Thanks

Check out sedFoam -- it might be useful for you : https://github.com/SedFoam/sedfoam.

Hi



Do you have any other suggestions Beacause it is mentionned that it's not fully operationnel and i dont want to test it Real CAse CFD.

I don't know what you mean by "real case cfd", but I would check out the sedFoam thread (sedFoam: two-phase flow sediment transport model). You might get different information there.

what i mean is that i dont want to fall in a senarion where the code still have bugs or maybe some errors that may lead me to innaccurate results or throught problems that i dont have time for . That's why i d prefer to use something that people already used before and made simulations with ..anyways i still gonna check the link and i really thank you for the reply .

There are two ways to simulate the sand + air, in other words, physics and math based meaning solid + gas flow.

1. Eulerian mathematical framework.
That's, following arbitrary amount of fluid particles and simulating flow.

2. Lagrangian mathematical framework.
That's, following arbitrary amount of fluid particles and simulating flow.

In terms of Euler framework, you'll be using, Volume of Fluid (VoF). The solver for using VOF is 'interFoam', and its variants such as interDyMFoam, etc.

For solving flows with Lagrangian framework, the particles are assisted along a specific finite volume domain.

Procedure to follow:
1. Simulate the exiting tutorials in 'interFoam', and 'twoPhaseEulerFoam' or Lagrangian folder tutorials such as the parcelFilmFoam.
2. modify the case with respect to your desired conditions, starting with '0' folder, that is modify the patch fields for boundary conditions.
3. Next modify the physical properties/ transport properties, choose non-newtonian model for transport model.
4. If needed then implement inter-granular models as well.
5. Run the case as the geometry requirement.
