air water sediment three phase flow
 

Hi,

I am trying to model a coastal engineering problem, and maybe Fluent is not very suitable for this kind of issue.

There is a pile-breakwater on wich are acting both regular and irregular waves. Id like to track the air-water interface (I know that the most suitable model is the multiphase VOF model) and at the same time to track bed sediment motion around piles.
Im quite sure that for the bed sediment the Euler model can be used.
You know that only one multiphase model can be chosen, thus I dont know if I should create two different models, the first to investigate the air-water interface and the second to check the sediment transport.
What do you think about this solution?
Or maybe someone knows if the usage of the mentioned models (VOF and Euler) for a three phase flow (air-water-sediment) is possible.

Any help or advice is appreciate.

Mat.
