Numerical simulation of biomass gas and tar torrential flow characteristics in cyclone separator

To settle the tar particle problem in eliminating tar from biomass gas by cyclone separator, the RSM model and DPM model were used to simulate three-dimensional strong rotating turbulent field in the cyclone separator. Contours of flow field in the cyclone separator were obtained, including dynamic pressure, turbulent kinetic energy, turbulence viscosity and velocity vector. The influence of the main factors in the cyclone separator on tar separating was analyzed. The results could provide reference for the improvement and optimization of the cyclone separator.
