- Dust grains should settle. What keeps them up? Does irradiation matter?
- Mixing due to macroscopic flows. But which?
RHD simulations with CO5BOLD
2D Cartesian box, 400x360 grid points,
1D approximate Riemann solver
- Radiation transport:
non-local, gas: non-grey 5-group opacity scheme (PHOENIX data)
dust opacities: simple, grey
- Monomers and dust:
2-bin or multi-bin
- Investigation of basic transport mechanisms for dust and gas
- Derivation of 1D mixing description to be included in PHOENIX
