Thus, in 2019, the so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized in numerical and experimental studies. Based on this research, a modification of the nozzle design was proposed, which has now been considered in the successor model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation on the particle formation, we operated both burners under identical operating conditions to produce maghemite. The final powder comparison showed that SS2 yielded considerable higher specific surface areas (associated with smaller primary particle sizes), lower polydispersity, and higher phase purity. To obtain further information on the size distributions of aggregates and agglomerates generated by SS2, aerosol samples were extracted by hole in a tube (HIAT) sampling and characterized by scanning mobility particle sizing (SMPS). Samples were extracted along the centerline at different heights above the burner (HAB) above the visible flame tip (>7 cm), and quenching experiments were performed to extract the aerosol samples at different dilution rates. Thereby, it was demonstrated that performing detailed quenching experiments is crucial for obtaining representative HIAT-SMPS data. In particular, agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were not sufficiently diluted. If sufficient dilution was applied, distribution widths and mean particle mobility diameters were determined with high accuracy (sample standard derivation <5 %). Our data suggested the evolution of primary particle sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates present above the visible flame were compact in structure (non- fractal). The mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7 cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52."}],"publication":"Applications in Energy and Combustion Science","department":[{"_id":"150"}],"type":"journal_editor","keyword":["Flame Spray Pyrolysis","SpraySyn2","Spray flame synthesis","Maghemite nanoparticles","Gas to particle-conversion","Hole in a tube sampling"],"date_created":"2024-02-05T12:02:57Z","has_accepted_license":"1","status":"public","editor":[{"full_name":"Tischendorf, Ricardo","first_name":"Ricardo","last_name":"Tischendorf","id":"67002"},{"id":"98419","full_name":"Massopo, Orlando","first_name":"Orlando","last_name":"Massopo"},{"id":"464","full_name":"Schmid, Hans-Joachim","last_name":"Schmid","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921"},{"last_name":"Pyrmak","first_name":"Olek","full_name":"Pyrmak, Olek"},{"full_name":"Dupont, Sophie","last_name":"Dupont","first_name":"Sophie"},{"full_name":"Fröde, Fabian","last_name":"Fröde","first_name":"Fabian"},{"full_name":"Pitsch, Heinz","first_name":"Heinz","last_name":"Pitsch"},{"last_name":"Kneer","first_name":"Reinhold","full_name":"Kneer, Reinhold"}],"user_id":"98419","ddc":["660"],"_id":"51133","publisher":"Elsevier","citation":{"short":"R.

A promising\r\nprocess to manufacture these nanoparticles is flame spray pyrolysis (FSP). A lack of understanding of the\r\nindividual sub-processes in FSP makes it challenging to tailor nanoparticle properties. This work provides\r\ninsights into the formation of iron oxide nanoparticles in a turbulent spray flame using Large Eddy Simulations\r\n(LES), which are based on a comprehensive model, including customized submodels. Highlights are the\r\nadaption of a turbulent combustion model and a bivariate hybrid method of moments for modeling nanoparticle\r\ndynamics. The work focuses on the SpraySyn burner, which is a standardized laboratory burner and was\r\noperated with a precursor-solvent mixture of ethanol and iron(III) nitrate nonahydrate. For studying the\r\nrelevance of precursor chemistry, LES using an evaporation-limited precursor chemistry model is compared\r\nwith a model that includes detailed iron chemistry. A further novelty is the inclusion of adsorption in the\r\nsimulation, which defines a third model for comparison. Sufficient validation is achieved for the undoped LES\r\nusing experimental data from the literature. A strong impact of the detailed iron chemistry and adsorption\r\nis found on the precursor consumption and the aggregate and primary particle formation. Comparing the\r\nparticle diameters with experimental measurements from the literature and data generated for this work is\r\nfound unsuitable to asses the precursor chemistry model and revealed an urgent need for future experimental\r\nand numerical research. This work serves as a step forward in realizing a reliable model."}],"publication":"Applications in Energy and Combustion Science","department":[{"_id":"150"}],"type":"journal_editor","keyword":["Flame spray pyrolysis","Iron oxide formation","Large eddy simulation","Method of moments","SpraySyn"],"date_created":"2024-02-05T12:17:35Z","publication_status":"published","date_updated":"2024-02-05T12:38:43Z","year":"2023","title":"Large eddy simulation of iron oxide formation in a laboratory spray flame","doi":"https://doi.org/10.1016/j.jaecs.2023.100191","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S2666352X23000808"}],"citation":{"bibtex":"@book{Fröde_Grenga_Pitsch_Dupont_Kneer_Tischendorf_Massopo_Schmid_2023, title={Large eddy simulation of iron oxide formation in a laboratory spray flame}, DOI={<a href=\"https://doi.org/10.1016/j.jaecs.2023.100191\">https://doi.org/10.1016/j.jaecs.2023.100191</a>}, journal={Applications in Energy and Combustion Science}, publisher={Elsevier}, year={2023} }","ama":"Fröde F, Grenga T, Pitsch H, et al., eds. <i>Large Eddy Simulation of Iron Oxide Formation in a Laboratory Spray Flame</i>.

This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values. Therefore, we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement of fresh concrete with particles up to <jats:inline-formula>\r\n                     <jats:alternatives>\r\n                        <jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"graphic/j_arh-2022-0140_eq_001.png\" />\r\n                        <m:math xmlns:m=\"http://www.w3.org/1998/Math/MathML\">\r\n                           <m:msub>\r\n                              <m:mrow>\r\n                                 <m:mi>d</m:mi>\r\n                              </m:mrow>\r\n                              <m:mrow>\r\n                                 <m:mi mathvariant=\"normal\">max</m:mi>\r\n                              </m:mrow>\r\n                           </m:msub>\r\n                           <m:mo>=</m:mo>\r\n                           <m:mn>5.5</m:mn>\r\n                           <m:mspace width=\".5em\" />\r\n                           <m:mi mathvariant=\"normal\">mm</m:mi>\r\n                        </m:math>\r\n                        <jats:tex-math>{d}_{{\\rm{\\max }}}=5.5\\hspace{.5em}{\\rm{mm}}</jats:tex-math>\r\n                     </jats:alternatives>\r\n                  </jats:inline-formula>. The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones.</jats:p>"}],"date_created":"2023-03-16T19:06:49Z","department":[{"_id":"150"}],"type":"journal_article","keyword":["Condensed Matter Physics","General Materials Science"],"author":[{"full_name":"Josch, Sebastian","last_name":"Josch","first_name":"Sebastian","id":"38243"},{"full_name":"Jesinghausen, Steffen","last_name":"Jesinghausen","first_name":"Steffen","orcid":"https://orcid.org/0000-0003-2611-5298","id":"3959"},{"id":"464","first_name":"Hans-Joachim","last_name":"Schmid","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim"}],"publication_identifier":{"issn":["1617-8106"]},"title":"Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete","year":"2023","intvolume":"        33","date_updated":"2023-04-27T11:19:08Z","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.degruyter.com/document/doi/10.1515/arh-2022-0140/html","open_access":"1"}],"doi":"10.1515/arh-2022-0140","citation":{"apa":"Josch, S., Jesinghausen, S., &#38; Schmid, H.-J.

For this purpose, dry blends of glass beads with and without organosilane coupling agents and polyamide powder were prepared and processed into tensile specimens on an EOS P396 laser sintering system. The samples were tested both in the dry state and after an accelerated conditioning in a climate chamber. Furthermore, finite element method (FEM) simulations were performed to model the extreme cases of optimum adhesion and no adhesion. By correlating the tensile tests with the simulation results and by analyzing the fracture surfaces, it was shown that the filler–matrix adhesion is sufficient in the dry state but is strongly degraded by conditioning. Even the presence of various organosilane thin films could not prevent a strong deterioration of the filler–matrix adhesion and the associated deterioration of the mechanical properties.
