摘要:
利用EDEM-FLUENT联合仿真，采用VOF法和欧拉-拉格朗日模型，组成离散固体与连续液相和气相的混合模型，对搅拌罐内固-液-气三相流动进行数值模拟，探究固体颗粒在搅拌罐内的运动状态和自由液面对其分散的影响。基于FLUENT软件的VOF法对气-液连续相建模，很好的捕捉气液分界面，模型更接近实际工况，直观显示自由液面的变化；基于离散元法软件EDEM对固体颗粒进行离散单元建模，通过两软件的联合仿真直观模拟固体颗粒在罐内的位置信息和运动情况，得到的固体颗粒扩散情况与利用欧拉法得到的结果相一致
Abstract:
By means of EDEM-FLUENT simulation and VOF(Volume of Fluid) method and Euler-Lagrangian model, a mixture model of discrete solid, continuous liquid and gas phase was constructed to simulate the three-phase flow with solid-liquid-gas in a stirring tank. The effect of the moving state of solid particles in stirring tank and free liquid level were explored. The gas-liquid continuous phase modeling based on VOF method using FLUENT software could capture gas-liquid interface well and the model was closer to the actual working condition. Based on the Discrete Element Method(DEM), the discrete element modeling of solid particles was established and its position information in the tank was simulated intuitively by the joint simulation of the two software. The dispersion of solid particles was consistent with the results obtained by Euler method.
