A sophisticated CAE workflow is used to calculate the operational characteristics of 50 machine designs with 50 impeller geometry variations each. A Kriging-based surrogate model is trained to approximate the efficiency of any machine designs' best geometry design. The models are implemented into a machine design workflow. As a result, duty-specific Cordier lines are introduced. They are automatically generated for a set of machine design parameters. The efficiency of the designs along the duty-specific Cordier lines is approximated. Using optimization techniques, an optimal compressor design for the given duty on every specific Cordier line may be identified. This highly increases the amount of information available in the early design stages for radial turbocompressors.}, language = {en} } @article{LattnerGeller2023, author = {Lattner, Yannick and Geller, Marius}, title = {Radial Turbocompressor Chord Length Approximation for the Reynold's Number Calculation}, doi = {10.26205/opus-3335}, url = {https://nbn-resolving.org/urn:nbn:de:hbz:dm13-33351}, year = {2023}, abstract = {We present an approximation model for the chord length of radial turbocompressors. The model enables the calculation of a compressor's chord Reynold's number during the machine design process. The chord Reynold's number is shown to be the most accurate representation of the fluid dynamic properties inside the radial turbocompressor's impeller. It — however — requires the computation of the chord length, which is only available after defining the final impeller geometry. The method presenting in this paper only employs the compressors principal dimensions to approximate the chord length. The chord is modelled using a B{\´e}zier spline and quarter ellipse. This enables the earlier use of the chord Reynold's number during the machine design process of radial turbocompressors.}, language = {en} } @incollection{CopeiEickhoffMaliketal.2022, author = {Copei, Sebastian and Eickhoff, Christoph and Malik, Adam and Nolte, Natascha and Norbisrath, Ulrich and Sorgalla, Jonas and Weber, Jens and Z{\"u}ndorf, Albert}, title = {From monolithic models to agile micromodels}, series = {Proceedings of the 10th International Conference on Model-Driven Engineering and Software Development}, publisher = {SciTePress}, address = {Set{\´u}bal}, pages = {227 -- 233}, year = {2022}, language = {en} } @incollection{Seco de HerreraIonescuM{\"u}lleretal.2022, author = {Seco de Herrera, Alba G. and Ionescu, Bogdan and M{\"u}ller, Henning and P{\´e}teri, Renaud and Ben Abacha, Asma and Friedrich, Christoph M. and R{\"u}ckert, Johannes and Bloch, Louise and Br{\"u}ngel, Raphael and Idrissi-Yaghir, Ahmad and Sch{\"a}fer, Henning and Kozlovski, Serge and Dicente Cid, Yashin and Kovalev, Vassili and Chamberlain, Jon and Clark, Adrian and Campello, Antonio and Schindler, Hugo and Deshayes, J{\´e}rome and Popescu, Adrian and Ştefan, Liviu-Daniel and Constantin, Mihai Gabriel and Dogariu, Mihai}, title = {ImageCLEF 2022: multimedia retrieval in medical, nature, fusion and internet applications}, series = {Advances in Information Retrieval: 44th European Conference on IR Research, ECIR 2022, Stavanger, Norway, April 10-14, 2022, Proceedings, Part II}, publisher = {Springer International Publishing}, address = {Cham}, pages = {382 -- 389}, year = {2022}, language = {en} } @book{OPUS4-3268, title = {The history of graphic design}, editor = {M{\"u}ller, Jens and Wiedemann, Julius}, publisher = {Taschen}, address = {K{\"o}ln}, isbn = {978-3-8365-8806-5}, pages = {511}, year = {2022}, language = {en} } @article{BrumannKukuk2022, author = {Brumann, Christopher and Kukuk, Markus}, title = {Evolution based single camera resectioning based on distance maps of a known geometry for Squash sports}, series = {IEEE Access}, issn = {2169-3536}, pages = {58136 -- 58150}, year = {2022}, language = {en} } @article{KremerKhaniAppeletal.2022, author = {Kremer, Robert and Khani, Somayeh and Appel, Tamara and Palkowski, Heinz and Foadian, Farzad}, title = {Selective laser melting of CuSn10: simulation of mechanical properties, microstructure, and residual stresses}, series = {Materials}, volume = {15 (2022)}, number = {11}, issn = {1996-1944}, pages = {1 -- 13}, year = {2022}, language = {en} } @article{Guias2022, author = {Guias, Flavius}, title = {On efficacy and effectiveness of vaccines}, series = {Spora : a journal of biomathematics}, volume = {8 (2022)}, issn = {2473-5493}, pages = {56 -- 60}, year = {2022}, language = {en} } @incollection{M{\"u}ller2022, author = {M{\"u}ller, Jens}, title = {A contribution to the history of graphic design}, series = {F{\´e}lix Beltr{\´a}n - visual intelligence: graphic design in a social sense}, publisher = {Optik Books}, address = {Dortmund}, pages = {8 -- 9}, year = {2022}, language = {en} } @incollection{BlochFriedrich2021, author = {Bloch, Louise and Friedrich, Christoph}, title = {Developing a machine learning workflow to explain black-box models for Alzheimer's disease classification}, series = {BIOSTEC 2021 : proceedings of the 14th International Joint Conference on Biomedical Engineering Systems and Technologies : online streaming, February 11-13, 2021}, publisher = {SCITEPRESS - Science and Technology Publications}, address = {S{\´e}tubal}, pages = {87 -- 99}, year = {2021}, language = {en} }
