While most of the previous work focused on layering in Couette cells, the present study aimed to characterize the resulting layers at the plates of a parallel plate rheometer with regard to their relative particle concentration. The particle concentration profile over the radial distance was characterized for various mean concentrations and gap heights. To this end, we mapped the distribution of fluorescently dyed tracer particles in density and refractive index matched suspensions. The results indicate that layering at the surfaces stabilizes as the ratio between gap height and particle diameter increases. For lower gap heights, i.e. as the suspension approaches a two dimensional state, the layer concentration was non-uniform over the plates. In general, results were quantitatively different for the upper and lower plate and the concentration profiles were noticeably asymmetric. We conclude that this is probably the result of the rheometer loading or the start-up process. The stable layers as well as the inhomogeneous particle distribution in general offer an explanation for the lack of transferability of viscosimetric results between different setups.","lang":"eng"}],"user_id":"70093","_id":"26118","language":[{"iso":"eng"}]},{"status":"public","type":"book","language":[{"iso":"ger"}],"department":[{"_id":"676"}],"user_id":"21240","_id":"27443","citation":{"apa":"Gausemeier, J., Schmidt, M., Anderl, R., Schmid, H.-J., Leyens, C., Seliger, G., Karg, M., &#38; Kage, M.

However, the manufacturability of lattice structures and mechanical properties for polymer laser sintering are quite unknown yet. To examine the manufacturability, sandwich structures with different cell types, cell sizes and lattice bar widths were designed, manufactured and evaluated. A decisive criterion is for example a sufficient powder removal. In a second step, manufacturable structures were analyzed using four-point-bending tests. Experimental data is compared to the density of the lattice structures and allows for a direct comparison of different cell types with varied geometrical attributes. The results of this work are guidelines for the design and dimensioning of laser sintered lattice structures.","lang":"eng"}],"user_id":"71545","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"_id":"22180","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"_id":"22185","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545","abstract":[{"text":"The layered structure of Additive Manufacturing processes results in a stair- stepping effect of the surface topographies. In general, the impact of this effect strongly depends on the build angle of a surface, whereas the overall surface roughness is additionally caused by the resolution of the specific AM process. The aim of this work is the prediction of the surface quality in dependence of the building orientation of a part. These results can finally be used to optimize the orientation to get a desired surface quality. As not all parts of the component surface are equally important, a preselection of areas can be used to improve the overall surface quality of relevant areas. The model uses the digital AMF format of a part. Each triangle is assigned with a roughness value and by testing different orientations the best one can be found. This approach needs a database for the surface qualities. This must be done separately for each Additive Manufacturing process and is shown exemplarily with a surface topography simulation for the laser sintering process.","lang":"eng"}],"status":"public","publication":"Additive Manufacturing","type":"journal_article","title":"Optimized build orientation of additive manufactured parts for improved surface quality and build time","doi":"10.1016/j.addma.2016.06.003","publisher":"Elsevier","date_updated":"2022-01-06T06:55:28Z","volume":2,"author":[{"first_name":"Patrick","last_name":"Delfs","full_name":"Delfs, Patrick"},{"first_name":"Marcel","full_name":"Tows, Marcel","last_name":"Tows"},{"last_name":"Schmid","full_name":"Schmid, Hans-Joachim","id":"464","first_name":"Hans-Joachim"}],"date_created":"2021-05-14T07:46:16Z","year":"2016","page":"214-320","intvolume":"         2","citation":{"ama":"Delfs P, Tows M, Schmid H-J.

For application of the technology in series production and an integration of laser sintered parts into a technical environment, the dimensional accuracy of parts has to be taken into account. Therefore, occuring deviatons and their scattering have to be reduced and homogenized based on process parameters and build job layout.

Nevertheless, the origin and the evolution are not completely clear yet. Regarding suspensions, the effect becomes even more complicated, because different mechanisms like pure slip or slip due to particle migration have to be taken into account. Furthermore, suspensions themselves show many flow anomalies and the isolation of slip is complicated. In order to develop working physical models, further insight is necessary. In this work, we measured experimentally the wall slip velocities of different highly filled suspensions in a rectangular slit die directly with respect to the particle concentration and the particle size. The slip velocities were obtained using a particle image velocimetry (PIV) system. The suspensions consisting of a castor oil–cinnamon oil blend and PMMA particles were matched in terms of refractive indexes to appear transparent. Hereby, possible optical path lengths larger than 15 mm were achieved. The slip velocities were found to be in a quadratic relation to the wall shear stress. Furthermore, the overall flow rate as well as the particle concentration has a direct influence on the slip. Concerning the shear stress, there seem to be two regions of slip with different physical characteristics. Furthermore, we estimated the slip layer thickness directly from the velocity profiles and propose a new interpretation. The PIV technique is used to investigate the viscosity and implicit the concentration profile in the slit die. It is shown that the particle migration process is quite fast.","lang":"eng"}],"status":"public","_id":"21947","department":[{"_id":"150"},{"_id":"9"}],"user_id":"3959","keyword":["Rheology","Wall Slip","Slip","apparent slip","suspension"],"article_type":"original","language":[{"iso":"eng"}]},{"year":"2016","citation":{"ama":"Pieper S, Schmid H-J.

This is commonly realized by diffusion charging of bipolar air ions generated by e.g. a 85Kr source. Because of strict legal regulations on radioactive sources in several countries, soft-X-ray (SXR) appears as a suitable alternative. However, multiple measurements showed a systematical and significant difference between the particle charge distribution delivered by a radioactive source and an SXR charger, respectively. In this investigation, a calibrated particle charge distribution, suitable for the SXR chargers, was calculated based on the Fuchs model. An approximation analogous to the commonly used Wiedensohler approximation formula (Wiedensohler, 1988) was computed. The use of the new SXR approximation of the bipolar charge equilibrium for the inversion of an electrical mobility distribution to a particle number size distribution improves the comparability of these results, compared to measurements involving a 85Kr charger or to bipolar chargers using radioactive material in general. A systematic error in case of using the SXR charger could be eliminated and hence the root mean square deviation could be reduced from 13% using the common parameters for both charger types to 7% using the new SXR approximation for the SXR bipolar charger.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Journal of Aerosol Science","language":[{"iso":"eng"}],"_id":"26121","user_id":"70093","year":"2015","citation":{"apa":"Tigges, L., Wiedensohler, A., Weinhold, K., Gandhi, J., &#38; Schmid, H.-J.

It is demonstrated, that the main influencing variable is the difference between the positive and negative ion mobility. A sensitivity analysis reveals that a reasonable variation of the ion mobilities may lead to variations of the particle density distribution up to±20%.\r\n\r\nThe second part investigates the evolution of the charge distribution along the tubing downstream of the bipolar charger exit starting with equal ion concentrations for positive and negative ions. Due to wall losses depending on ion mobility a non-equilibrium charge distribution is developing along the plumbing. The evolution of the particle charge distribution is determined using a coupled population balance model.

Biomass burners are one important example for ultrafine dust emission sources with ever growing importance. Therefore, a baghouse filter has been developed, which combines excellent separation efficiency (> 99%, clean air dust loading of < 1 mg/m3) with convenience in operation. However, in order to prevent clogging of the filter cloth by sticky and ultrafine particles, it is necessary to use a precoat layer (e.g. hydrated limestone powder). If this technology is applied to larger scale processes, e.g. biomass burning for industrial drying processes, the reuse of the precoat material can generate significant savings.\r\n\r\nTherefore, extended tests on recycling of used precoat material have been performed. Particularly, the influence of precoat injection parameters and various mixing strategies of used and virgin powder for refreshing the precoat material have been investigated. Different mixtures have been characterised by their ability to disintegrate, flowability and filtration behaviour. It is clearly demonstrated that upon redispersing the used precoat fine dust mainly adheres to the coarse precoat with only a limited number of dust agglomerates being produced in addition. For each kind of precoat a minimum amount is determined in order to ensure a long-term stable process.

The results of this work help to understand the temperature history dependency of powder and part properties and can therefore be used to develop optimized process controls."}],"status":"public","date_updated":"2022-01-06T06:55:28Z","author":[{"first_name":"Stefan","last_name":"Josupeit","full_name":"Josupeit, Stefan"},{"last_name":"Schmid","id":"464","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"}],"date_created":"2021-05-14T07:46:09Z","volume":26,"title":"Temperature History within Laser Sintered Part Cakes and its Influence on Process Quality","doi":"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf","year":"2015","citation":{"bibtex":"@inproceedings{Josupeit_Schmid_2015, title={Temperature History within Laser Sintered Part Cakes and its Influence on Process Quality}, volume={26}, DOI={<a href=\"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf\">http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf</a>}, booktitle={26th Annual International Solid Freeform Fabrication Symposium}, author={Josupeit, Stefan and Schmid, Hans-Joachim}, year={2015}, pages={190–199} }","mla":"Josupeit, Stefan, and Hans-Joachim Schmid. “Temperature History within Laser Sintered Part Cakes and Its Influence on Process Quality.” <i>26th Annual International Solid Freeform Fabrication Symposium</i>, vol. 26, 2015, pp. 190–99, doi:<a href=\"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf\">http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf</a>.","short":"S.
