title = "Numerical investigation of gas-solid two phase flow over composite structures of elbow and venturi tube",
abstract = "The Euler-Lagrange method and Dispersed Phase Model (DPM) are adopted in the numerical simulation of gas-solid two-phase flow inside elbow, venturi tube and a new rich-lean pulverized coal burner combined elbow and venturi tube. It is to study the characteristic of coal distribution and the outlet characteristics of rich/lean separation influenced by pulverized coal particle diameter and density. he Detached-eddy-simulation (DES) approach is involved in the calculation of turbulence dispersion of gas phase. The Discrete random walk model (DRW) is used in the turbulence of solid phase. The results show that, for the particles of smaller diameter (10μm), the effect of rich-lean separation of three types of structure is unobvious; for the particles of larger diameter (50μm), this new structure burner can achieve rich-lean separation and the maximum concentration rises as the Stokes number increases; for the particles of more larger diameter 100μm, with the increasing number of St, there will be more than one core of concentration.",
