Hello I am new in fluent. I want to examine the erosion of the pipe due to liquid-solid flow. The mixture of solids and liquid come from the same source that is inserted into the pipe at a certain speed. Volume fraction of solids is more than 15%. The characteristic of the flow is turbulent with Re reaches 300000.

Because I want to see the erosion of the pipe caused by the solid particles, then I use a dense discrete phase model in the Eulerian multiphase model with one Eulerian phase (the liquid) and one discrete phase (the solid particles)

I use a standard k-epsilon viscous models. And the boundaries that I use are velocity inlet, outlet pressure and wall.

Is there anything else I need to consider? I doubt whether the model that I use is correct or not, because I do not get the convergent result.

Thanks
