COMPARING TURBULENCE MODELS FOR GAS-PARTICLE MIXTURE PNEUMATIC CONVEYING
Abstract eng: The system of transport tertiary air in cement kiln installation is one of the elements, which has the very large influence on production processing. This paper analyses numerical calculation in the installation for tertiary air in a cement plant. The operation condition of the installation is to ensure transport of gas with the smallest number of particles. By comparing several turbulence models used for calculation gas phase motion and Lagrangian model for discrete phase one can find an optimal solution. The particle trajectories depend on velocity field in researched models. For analyzed examples, the same pressure drop between inlet and outlet to the tertiary air duct were set.
