Abstract

In this study a new hybrid RANS/LES turbulence model within the frame work of the Multi Relaxation Time (MRT) Lattice Boltzmann method (LBM) was used to study particle dispersion and deposition in a room. For the hybrid RANS/LES method the near wall region was simulated by the RANS model, while the rest of the domain was analyzed using the LES model within the framework of the LBM. In the near wall layer where RANS was used, the turbulence model was employed. To simulate the particle dispersion and deposition in the room, particles with diameters of 10nm to 10 µm were investigated. The simulated results for particle dispersion and deposition showed that the predictions of the present hybrid method were quite similar to the earlier LES-LBM.   In addition, the predictions of the hybrid model for the particle deposition and dispersion were closer to LES simulation results compared to those of the  model.
