Study On Computational Dynamic Simulation Of Vane Mist Eliminator

Flow filed distribution in curved duct of vane type mist eliminator is discussed in this paper. Gas-liquid two-phase flow field in Vane Mist Eliminator is described by N-S equation group. model and Particle-Track model is utilized for the closure of the time-averaged equation group. Differnntial equations are discretized to difference equation by finite difference method. The effects of height, turning angle , spacings and gas velocity on pressure drop and removal efficiency are analyzed finally. The results of numerical simulation are in good agreement with experimental datas. Large-scale in common fluid calculation procedure is used to write procedure in this thesis. The procedure language is a language two times set up in calculating various kinds of computing functions of hydrodynamics, have well achieved the re-set goal. The result of calculation has proved the influence of many kinds of structure parameter and operate parameter on pressure drop and removal efficiency of vane type mist eliminator. It is proved to be convenient and ocular of using large-scale calculation procedure to simulate gas liquid two-phase of vane type mist eliminator. Hua Wei (Environmental Engineering)Directed by prof.
