| 摘 要： | In this work,an Eulerian/Lagrangian approach has been employed to investigate numerically the flowcharacteristics,heat transfer and combustion in a tangentially fired furnace.The RNG(Re-normalization group)κ-εmodel and a new method for cell face velocity interpolation based on a non-staggered grid system are employed.Toavoid pseudo-diffusion that is significant in modeling tangentially fired furnaces,attempts are made at improving thedifferential volume scheme.Some new developments on turbulent diffusion of particles are also taken into account.Thus,computational accuracy is improved substantially.

| Abstract: | In this work, an Eulerian/Lagrangian approach has been employed to investigate numerically the flow characteristics, heat transfer and combustion in a tangentially fired furnace. The RNG (Re-normalization group) k-e model and a new method for cell face velocity interpolation based on a non-staggered grid system are employed. To avoid pseudo-diffusion that is significant in modeling tangentially fired furnaces, attempts are made at improving the differential volume scheme. Some new developments on turbulent diffusion of particles are also taken into account. Thus, computational accuracy is improved substantially. |
