Dear fuc!@#$#* like me!!!

I need simulate a three phase flow phenomena that involve two immiscible fluid, air and water, and a third miscible fluid, sand. The air and water will be modeled as a free surface flow inside a horizontal tube. Because the gravity force the water will stay in the botton portion of the tube and the air in the top. The sand will be modeled as an eulerian dispersed fluid in the botton of the tube.

What the best way?
1º Use the VOF + Level Set model with geometric reconstruction for modling air and water and try to implement a udf code for third eulerian dispersed phase like a sand, or
2º Try to implement a Level Set method (interface tracking correction) for improvement of VOF in a Multi-Fluid VOF Model?

Thanks to much!!!!
