ATCx DEM 2020 - DEM modeling of particulate processes – from conceptualization to industrial application

The Discrete Element Method (DEM) is increasingly being used to simulate powders and particulates that are common in many industrial and natural processes. Since DEM computes at individual particle level, it has the potential to capture the underlying particle phenomena of a problem such as friction, cohesion or breakage, which in turn informs the bulk industrial process of interest. Using a few examples, this presentation will discuss model conceptualization of problems in developing effective solutions to address challenging industrial problems.

ATCx DEM 2020 - Optimizing pneumatic conveying of cohesive dairy powders using EDEM–CFD coupling

Pneumatic conveying pipelines undergo series of direction changes due to space restrictions, site location, or position of receiving silos and hoppers. When dairy powder and air flows around pipe bends or experiences any change in flow direction during pneumatic conveying, the particles form a rope-like structure due to inertial, gravitational and centrifugal effects. The formation of such particle ropes can lead to particle stratification, re-agglomeration, deposition, and pipe blockages especially when handling cohesive powders.

This research focuses on the design and optimization of novel flow-aided pipe bends that prevents powder deposition, pipe clogging, and improves throughput. Several conceptual designs of such flow-aids are investigated for various bend orientation by coupling Altair EDEM with Computational Fluid Dynamics (CFD) supported with targeted experimentation. The optimum flow-aided design integrated into a pilot-scale conveying test rig results in higher rope dispersion after the than similar test rig with conventional bends.

ATCx DEM 2020 - A model for simulating particle breakage with high fidelity in EDEM

Desired or not, particle breakage can occur when dealing with particulate materials in industry. For cases in which breakage severely influences the flow of the material, the only viable option is to describe it within the DEM environment. Several powerful approaches have been proposed over the years, but only very few are suitable to be used in large-scale simulations.

The presentation shows one such model that has been implemented in Altair EDEM to describe body breakage of brittle materials. It is based on a novel stochastic particle replacement approach involving spheres. It accounts for variability and size-dependence of fracture energies, besides weakening when particles do not break and fragment size distribution dependent on stressing energy. Results from model verification and validation in EDEM are presented, which demonstrate its high fidelity, besides examples of application to predict breakage in selected crushers.

ATCx DEM 2020 - DEM applications in pharmaceutical manufacturing processes

Particle processing is one of the core activity of pharmaceutical products and processes development, manufacturing, and also drug delivery. The powder behavior and processing performance have direct impacts on process robustness, yield, and final product performance (drug delivery). 

Product and process development efforts are normally time consuming and expensive by experimental trial-and-error approach. Discrete Element Method (DEM) modeling, and other mechanistic methods, are enabling tools for creating a digital sandbox. Engineering can utilize these tools for equipment characterization, process parameter optimization, target performance tuning, rapid process development and cost saving, and eventually delivering product faster to the market (patients benefits). The applications are diverse, from batch or continuous blending, micronization, tablet making, coating, or using CFD-DEM methods for dry powder inhalers and drug delivery. 

In this presentation the applications of DEM and CFD-DEM modeling in pharmaceutical manufacturing will be discussed. Critical aspects of the model development, validation, and implementation in compliance with regulatory criteria will be explained.

ATCx DEM 2020 - Wear simulation using automated geometric deformation with the discrete element method

Tools used in soil cultivation are subject to heavy wear. Simulation methods, such as the Discrete Element Method (DEM), show a good suitability to analyze these processes. In materials science, many investigations of wear are based on the scratch test, in which a diamond tip is moved along a material surface and the volume removed provides information about the abrasion behavior. With the DEM it is possible to simulate this scratch test virtually.

During the simulation of the stress, no geometric deformation according to the expected wear takes place so far. For this purpose, a program has been developed which changes the geometry of the tool to be examined at defined intervals as a CAD model and returns it to the simulation. The interaction is automated, so that no manual adjustments are necessary and the wear process can be displayed in any detail.
