## Multiphase - Dispersed Solvers

Dispersed Solvers In this group, we have included solvers implementing the **Eulerian** or **Lagrangian** approach to handle multiple fluids and particle clouds considering **Dispersed Phases** or **Fluid-Particle interactions**.

**Dispersed - Euler**

- [multiphaseEulerFoam](https://help.sim-flow.com/solvers/multiphase-euler-foam) multiple miscible fluids, Euler-Euler approach

**Dispersed - Lagrangian**

- [DPMFoam](https://help.sim-flow.com/solvers/dpm-foam) 1 fluid and particles, particle-particle interactions resolved explicitly (direct approach)
- [MPPICFoam](https://help.sim-flow.com/solvers/mppic-foam) 1 fluid and particles, dense particle cloud using particle-particle interactions model (simplified approach, MP-PIC method)

- [DPMDyMFoam](https://help.sim-flow.com/solvers/dpm-dym-foam) extension of DPMFoam with DyM
- [MPPICDyMFoam](https://help.sim-flow.com/solvers/mppic-dym-foam) extension of MPPICFoam with DyM

**Dispersed - Drift-Flux**

- [driftFluxFoam](https://help.sim-flow.com/solvers/drift-flux-foam) 1 fluid and slurry or plastic dispersed phase, drift flux approximation for relative phase motion

- DPM - Discrete Phase Model
- MP-PIC - multiphase particle-in-cell method
- DyM - Dynamic Mesh

1. 1. All solvers are transient and capable of accommodating buoyancy forces.
2. 2. Additionally, these solvers support:
   - RANS/LES turbulence models
   - Porosity models
   - MRF (except multiphaseEulerFoam)
   - Passive scalar
   - Custom source term (except multiphaseEulerFoam)
