| Abstract: | This paper investigates a new rich-lean pulverized coal burner combined elbow and Venturi tube.The gas-solid two-phase flow inside elbow,Venturi tube and this new structure are simulated numerically.The Euler-Lagrange method and Dispersed Phase Model(DPM) are adopted in the studies of gas-solid two-phase flow.The 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 ... |
