Suspended sediments and oil slicks in rivers

serper · February 18, 2014, 18:39

Hello, I am interested in using CFD to model the interaction of oil spills with suspended sediments in river rapids - I have some experimental results from a small shaking apparatus that could be used for model verification.

I would like to be able to predict to what degree the suspended sediments will cling to oil droplets in real rapids and eventually sink the slick, as happens in the lab. I can't run a test in a real river, as you can imagine.

Is this within the capabilities of OF, and if so, can someone recommend which solver to use? The sediments are very small (clay size range).

Thank you.

You have to do a search for Flocculation and CFD. For the most part ,this forum has a few postings of users asking for help, but those threads didn't seem to go anywhere. If you search on Google for "Flocculation OpenFOAM" or "Flocculation CFD". For the first terms, there is even a posting for a research job. I think the scale at which you wish to model the phenomena is important too. It would be different if you wish to model particles aggregating or you wish to input parameters and estimate what will happen on a section of a river. Some of the work done in emulsions might be relevant too.

Thank you for the response. I will give it a try.
Best regards.

Look into DPMFoam, whose capabilities have been reviewed by https://repositorium.sdum.uminho.pt/handle/1822/39328
