Default Eulerian air-particles: Solid pressure or Granular pressure?

Haldis is on a distinguished road

I am using the Eulerian multiphase model to simulate an air-particle flow. The volumefraction of the particles is rather high (initial 0.6), so I need to include particle-particle interactions. Which model should I choose, the solid pressure model or the granular pressure model? Thank you in advance for advices!
