  • Chitsazan, Ali; Klepp, Georg; Glasmacher, Birgit (Columbia, Mo. : Global Digital Central, 2022)
    The effect of jet Reynolds number, jet exit angle, the nozzle to surface distance, jet to jet spacing on the heat transfer, and pressure force performance from multiple impinging round jets on a moving curved surface have ...
  • Chitsazan, Ali; Klepp, Georg; Chitsazan, Mohammad Esmaeil; Glasmacher, Birgit (Columbia, Mo. : Global Digital Central, 2022)
    For the optimization of the impinging round jet, the pressure force coefficient and drying energy consumption on the moving curved surface are set as the objective functions to be minimized simultaneously. SHERPA search ...
  • Chitsazan, Ali; Klepp, Georg; Glasmacher, Birgit (Columbia, Mo. : Global Digital Central, 2022)
    The effect of surface curvature, number of jets, number of jet rows, jet arrangement, crossflow, and surface motion on the heat transfer and pressure force performance from multiple impinging round jets on the moving flat ...
  • Oel, Marcus; Gembarski, Paul Christoph; Lachmayer, Roland (Novi Sad : University of Novi Sad - Faculty of Technical Sciences, 2022)
    In order to meet a wide range of customer requirements in product development, a high degree of individualization is necessary today, which can be achieved with product configuration systems. Knowledge-based CAD models are ...
  • Heikebrügge, S.; Ottermann, R.; Breidenstein, B.; Wurz, M.C.; Dencker, F. (Boston, Mass. : Springer, 2022)
    Background: Commonly, polymer foil-based strain gauges are used for the incremental hole drilling method to obtain residual stress depth profiles. These polymer foil-based strain gauges are prone to errors due to application ...
  • Gedik, Aydan; Lubos, Nico; Kabelac, Stephan (Basel : MDPI, 2022)
    With its outstanding performance characteristics, the SOFC represents a promising technology for integration into the current energy supply system. For cell development and optimization, a reliable quantitative description ...
  • Hollmann, Jan; Fuchs, Marco; Spieker, Carsten; Gardemann, Ulrich; Steffen, Michael; Luo, Xing; Kabelac, Stephan (Basel : MDPI, 2022)
    A laboratory-scale solid oxide fuel cell (SOFC) system using liquefied natural gas (LNG) as a fuel is designed to be used as an energy converter on seagoing vessels (MultiSchIBZ project). The presented system design phase ...
  • Neto, Alfredo Gay; Wriggers, Peter (Berlin ; Heidelberg [u.a.] : Springer, 2021)
    We present a version of the Discrete Element Method considering the particles as rigid polyhedra. The Principle of Virtual Work is employed as basis for a multibody dynamics model. Each particle surface is split into ...
  • Bode, T.; Weißenfels, C.; Wriggers, P. (Berlin ; Heidelberg : Springer, 2022)
    This work presents a meshfree particle scheme designed for arbitrary deformations that possess the accuracy and properties of the Finite-Element-Method. The accuracy is maintained even with arbitrary particle distributions. ...
  • Wriggers, P.; Hudobivnik, B.; Allix, O. (Berlin ; Heidelberg : Springer, 2021)
    The virtual element method allows to revisit the construction of Kirchhoff-Love elements because the C1-continuity condition is much easier to handle in the VEM framework than in the traditional Finite Elements methodology. ...
  • Gembarski, Paul Christoph; Gast, Pauline (Novi Sad : University of Novi Sad - Faculty of Technical Sciences, 2022)
    Knowledge-based geometry models reduce variant design to the input of parameter values. Especially knowledge-based CAD models that incorporate geometrical data and implemented explicit knowledge offer additional possibilities. ...
  • Gembarski, Paul Christoph (Novi Sad : University of Novi Sad - Faculty of Technical Sciences, 2022)
    Design automation systems often mimic human designers and implement routine design activities. Beside this, the idea of such knowledge-based engineering is to support developers in the analysis and syntheses of complex ...
  • Plappert, Stefan; Becker, Christian; Gembarski, Paul Christoph; Lachmayer, Roland (Novi Sad : University of Novi Sad - Faculty of Technical Sciences, 2022)
    During product development, changes to parts that are already built into assemblies usually lead to the need to check the function and consistency of the assembly. This procedure is very time-consuming and has to be performed ...
  • Wolf, Mario; Rehder, Lena; Steinbach, Frank; Abt, Marvin; Hinterding, Richard; Overmeyer, Ludger; Feldhoff, Armin (Weinheim : Wiley-VCH Verl., 2021)
    The manufacturing technology of thermoelectric materials is laborious and expensive often including complex and time-intensive preparation steps. In this work, a laser sintering process of the oxide-based thermoelectric ...
  • Munoz Osorio, Juan David (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Robots are becoming more than machines performing repetitive tasks behind safety fences, and are expected to perform multiple complex tasks and work together with a human. For that purpose, modern robots are commonly built ...
  • Tatzko, Sebastian; Ehlers, Tobias; Kleyman, Gleb; Lachmayer, Roland (Lyon : Université de Lyon, 2022-07-22)
    Additively manufactured parts are often created with cavities for weight reduction or other mechanical purposes. These cavities offer the optimal base for granular damping. Unfused raw material particles can be left inside ...
  • Noii, Nima; Khodadadian, Amirreza; Ulloa, Jacinto; Aldakheel, Fadi; Wick, Thomas; François, Stijn; Wriggers, Peter (Dordrecht [u.a.] ; Berlin ; Heidelberg : Springer, 2022)
    The complexity of many problems in computational mechanics calls for reliable programming codes and accurate simulation systems. Typically, simulation responses strongly depend on material and model parameters, where one ...
  • Wriggers, Peter (Berlin ; Heidelberg [u.a.] : Springer, 2022)
    The virtual element method (VEM) was developed not too long ago, starting with the paper [2] related to elasticity in solid mechanics. The virtual element method allows to revisit the construction of different elements; ...
  • Köhler, Maximilian; Junker, Philipp; Balzani, Daniel (Berlin ; Heidelberg [u.a.] : Springer, 2022)
    In this paper, we propose a novel, semi-analytic approach for the two-scale, computational modeling of concentration transport in packed bed reactors. Within the reactor, catalytic pellets are stacked, which alter the ...
  • Ehlers, Tobias; Lachmayer, Roland (Basel : MDPI, 2022)
    Additively manufactured particle dampers can significantly improve component damping. However, if designed incorrectly, the damping can be worsened. For the design of additively manufactured particle dampers, there are not ...
