Simulating erosion on pelton buckets by silt laden flow
 

Simulating the erosion by virtue of sediment particles laden in silt water on the buckets of Pelton turbine in a steady state using Frozen rotor.

Performed the multiphase analysis (air+water) both as the continuous phase (Eullarian) with solid particle (particle tracking ).

When I do so the warning message pops out as "In Analysis 'Flow Analysis 1' - Domain 'Stationary': Particle tracking simulations with more than one continuous Eulerian phase are not supported".

Came across a document released by ANSYS 2016 (document attached) to tackle such warning. The method defined in that document is about changing expert parameters. I am not able to find the expert parameter "pt multiphase = t" and expert parameter "pt multiphase min volfrc = 0.5" mentioned in the document attached.

In addition to this I am a bit confused in choosing the following options

1. What reference density should I use?

a.) Air

b.) water
