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} } @article{W{\"u}stBongertGelleretal.2019, author = {W{\"u}st, Jan and Bongert, Markus and Geller, Marius and Strauch, Justus and Buchwald, Dirk}, title = {In-silico-Studie der Einfl{\"u}sse der kontundierenden Geometrie auf die Blutstr{\"o}mung hinter einer Schlauchklemme}, series = {Kardiotechnik}, volume = {28 (2019)}, number = {Supplement 01}, issn = {0941-2670}, pages = {9 -- 9}, year = {2019}, language = {de} } @article{BongertGellerPennekampetal.2019, author = {Bongert, Markus and Geller, Marius and Pennekamp, Werner and Volkmar, Nicolas}, title = {Simulation of personalised haemodynamics by various mounting positions of a prosthetic valve using computational fluid dynamics}, series = {Biomedical engineering/Biomedizinische Technik}, volume = {64 (2019)}, number = {2}, issn = {1862-278X}, pages = {147 -- 156}, year = {2019}, language = {en} } @article{BongertGehronGelleretal.2018, author = {Bongert, Markus and Gehron, Johannes and Geller, Marius and B{\"o}ning, A. and Grieshaber, Philippe}, title = {Bernoulli effect aggravates leg malperfusion during extracorporeal life support with femoral arterial cannulation}, series = {The Thoracic and Cardiovascular Surgeon}, volume = {2018}, number = {S01}, issn = {0040-6384}, year = {2018}, language = {en} } @article{GellerKluckSchemmann2012, author = {Geller, Marius and Kluck, Norbert and Schemmann, Christoph}, title = {Simulation radialer Gleitlager}, series = {Economic engineering : das Wirtschaftsfachmagazin f{\"u}r Ingenieure}, number = {4}, issn = {1866-5004}, pages = {3}, year = {2012}, language = {de} } @article{GellerSchemmannKluck2012, author = {Geller, Marius and Schemmann, Christoph and Kluck, Norbert}, title = {Robustness evaluation and RDO of a centrifugal compressor impeller}, series = {RDO-Journal}, number = {1}, pages = {2}, year = {2012}, language = {en} } @article{GellerSchemmannKluck2014, author = {Geller, Marius and Schemmann, Christoph and Kluck, Norbert}, title = {Simulation of radial journal bearings using the FSI approach and a multi-phase model with integrated cavitation}, series = {Progress in computational fluid dynamics : an international journal}, volume = {14 (2014)}, number = {1}, issn = {1468-4349}, pages = {1}, year = {2014}, language = {en} } @article{GellerSchemmannKluck2012, author = {Geller, Marius and Schemmann, Christoph and Kluck, Norbert}, title = {Gleiten nur zum Schein}, series = {Antriebstechnik}, number = {11}, issn = {0722-8546}, pages = {4}, year = {2012}, language = {de} } @article{BongertGellerStrauch2015, author = {Bongert, Markus and Geller, Marius and Strauch, J.}, title = {Untersuchung der Rezirkulation der Blutstr{\"o}mung im rechten Vorhof beim Einsatz einer VV-ECMO}, series = {CAME : Computer aided medical engineering}, volume = {6 (2015)}, number = {1}, issn = {2190-0698}, pages = {7}, year = {2015}, language = {de} } @article{BongertGellerPennekamp2014, author = {Bongert, Markus and Geller, Marius and Pennekamp, Werner}, title = {In silico model of a patient specific Aorta using 4D-MRI data simulating the hemodynamic effects of mechanical aortic valve}, series = {Biomedical engineering/Biomedizinische Technik}, volume = {59 (2014)}, number = {s1}, issn = {1862-278X}, pages = {19}, year = {2014}, language = {en} }
