CFD Simulations
Overview of CFD Simulations
LES and RANS simulations were carried out in the benchmark geometry. The details of these numerical tests and their predicted deposition are given in the following paragraphs. In summary, the main differences in LES and RANS simulations are:
- Computational meshes
- Turbulence modeling
- Different outlet boundary conditions
- In RANS simulations a turbulent dispersion model was used to account for the effect of turbulence on particle transport.
Large Eddy Simulations
Computational domain and meshes
The geometry used in the calculations is the same as the one used in the experiments developed by the group in Brno University of Technology (BUT). The computational domain, shown in Figure 10, has one inlet and ten different outlets, for which appropriate boundary conditions must be specified in the simulations.
