κ-ε turbulence model,Eulerian model and discrete phase model(DPM) were used in the simulation of three-dimensional two-phase flow in the new type wet dedusting and desulphurization tower with umbrella type plates by using FLUENT package,and SIMPLE algorithm was used in the calculation.

利用FLUENT软件对新型的伞罩型湿法除尘脱硫塔内的三维二相流场进行数值模拟,气相采用κ-ε湍流模型,颗粒相采用离散相模型(DPM)和欧拉模型,选择SIMPLEC算法进行计算。
