The Dense Discrete Phase Model coupled with an agglomeration model is developed and validated for the simulation of industrial cyclones with high solid loads. The performance of the model is influenced by sub-models, model parameters, and numerical parameters. To optimize the performance of the prese...
The case study evaluates the predictive performance of the coupled hybrid 3-D computational fluid dynamics-dense discrete phase model (CFD-DDPM) approach implemented into the commercial general purpose code ANSYS-Fluent R16.2, when applied to industrial cyclone collectors used to separate particles from...

利用DDPM和DEM模拟鼓泡流化床 (fluent) DEM碰撞模型扩展了DPM模型的功能,能够用于稠密颗粒流动的模拟。该模型可以与DDPM(Dense DPM)模型何用以模拟颗粒对主相的阻碍作用,因此可以用于鼓泡流化床、提升管、气力输送系统以及泥浆流动。特别对于以下情况,DEM模型特别有用:当颗粒粒径分布很广时;当计算网格相对粗糙时。
DDPM (dem) model specifying collisions with boundaries #1 grasingerm New Member PA Join Date: May 2014 Posts: 6 Rep Power:12 I am trying to start with a simple discrete element model in fluent. I ran an unsteady model with unsteady particle tracking and the DEM collision model ...
The simulation of particles residence time distribution (RTD) in a gas-solid cyclone reactor (GSCR) based on the CFD-DDPM tracer method was conducted. The comparison between the computed results and the experimental data shows that this model is applicable to predict the gas-solid hydrodynamics ...
