As material models for the DEM are limited in the accuracy of particle shape representation, behaviour of bulk material can deviate between simulations and reality. Therefore, a defined approach for developing material models is required in order to improve the accuracy of numeric simulations. This need is intensified, as recycling processes with direct processing of regrind with complex particle shapes become more common. In this paper, an approach commonly referred to as calibration is applied to several polymer pellets as well as regrind. The approach is altered in order to produce accurate models suited to replicate the conditions (flow conditions, pressure and relative movement) occurring during polymer processing in screw machines. A method for material model development is defined, focusing on calibrating the coefficient of rolling friction based on an angle of repose test and subsequently assessing the representation of the coefficients of friction in a shear cell and bulk density in annular-recess-shaped containers. The developed single- and multi-sphere models can be used for further investigations on the behaviour of polymer processing screw machines.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 8","pages":"Article 104968"},"PeriodicalIF":4.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study utilized a condensational particle growth system to improve the aerosol particle charging efficiency and electric virtual impactor performance. A condensational particle growth system and a corona-needle unipolar charger were used together. Polydisperse particles ranging from 10 nm to 5 μm were grown to bigger droplets and charged to a high charge level in the corona needle charger before drying them in the evaporator. A charge level of more than 50 charges per particle was achieved for sizes of 20, 30, 42, and 55 nm. The highly charged particles were then sampled in the electric virtual impactor. The lower cutoff size of the electric virtual impactor could vary in the range from 30 nm to 1 μm while the upper cutoff size was fixed to 2.5 μm based on inertial separation mechanism.

In this study, six types of flake aluminum powders and six types of spherical aluminum powders were selected for a comparative investigation of their microstructural characteristics and combustion performance, employing techniques of Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X-ray Diffraction (XRD), and oxygen bomb calorimetry. Additionally, research was conducted on the chip self-destruction technology based on aluminum powder. The results indicate that as the particle size of flake aluminum powder increases, the content of reactive aluminum also rises, leading to enhanced combustion heat value. Smaller-sized flake aluminum powders exhibited agglomeration phenomena. The condensed combustion products of flake aluminum powder are composed of dispersed gray-white particles, with multiple smaller fragments present. The smaller the particle size of the flake aluminum powder, the more dispersed its combustion products appear upon solidification; conversely, larger particles tend to coalesce. The primary composition of the combustion products of flake aluminum powders consists of 3Al<sub>2</sub>O<sub>3</sub>·2SiO<sub>2</sub> and Al<sub>2</sub>O<sub>3</sub> crystals. For spherical aluminum powders, both the combustion heat value and efficiency increase with larger particle size, with notable differences observed between nano-sized and micron-sized aluminum powders regarding combustion heat value and efficiency. The combustion products of spherical aluminum powders consist of closely adhered black and white condensed phase combustion products, along with a few gray-white particles distributed on the walls and bottom of the crucible. The ignition process of both flake and spherical aluminum powder composite fuels comprises five stages: ignition, deflagration, stable combustion, flame decay, and extinguishing, with significant effects of the microstructural differences in aluminum powders on each stage. The ignition delay time for flake aluminum powders is shorter than that for spherical aluminum powders, accompanied by a higher intensity of combustion, indicating greater flammability, while spherical aluminum powders exhibit longer combustion durations. Both flake aluminum powder composite fuels and spherical aluminum powder composite fuels can cause irreversible physical damage to chips and their leads, achieving effective destruction.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 8","pages":"Article 104964"},"PeriodicalIF":4.2,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
