  • Aerodynamic feeding systems: An example for changeable technology 
    Frädrich, Thomas; Pachow-Frauenhofer, Julia; Fiege, Torsten; Nyhuis, Peter (Bingley : Emerald Group Publishing Ltd., 2011)
    Purpose - The purpose of this paper is to transfer the idea of changeability to a concrete technical application. Design/methodology/approach - Based on the definition of changeability on a factory level, a transformation ...
  • Aerodynamical and Structural Analysis of Operationally Used Turbine Blades 
    Schwerdt, Lukas; Hauptmann, Thomas; Kunin, Artsem; Seume, Jörg R.; Wallaschek, Jörg; Wriggers, Peter; Panning-von Scheidt, Lars; Löhnert, Stefan (Amsterdam : Elsevier BV, 2017)
    This paper presents an integrated methodology for the analysis of operationally-used turbine blades, incorporating aerodynamic and multiple structural simulations. In jet engines, blade rubbing and erosion lead to deviations ...
  • Design and test of a 10kW ORC supersonic turbine generator 
    Seume, Jörg R.; Peters, M.; Kunte, H. (Bristol : Institute of Physics Publishing, 2017)
    Manufactures are searching for possibilities to increase the efficiency of combustion engines by using the remaining energy of the exhaust gas. One possibility to recover some of this thermal energy is an organic Rankine ...
  • Differential infrared thermography for rotor aerodynamics 
    Wolf, Claus Christian (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    Understanding the flow around helicopter rotors is one of the greatest challenges in modern aerodynamics. The flow field plays a key role in the rotorcraft performance and operational safety, and it is characterized by ...
  • Implementation and Testing of a Genetic Algorithm for a Self-learning and Automated Parameterisation of an Aerodynamic Feeding System 
    Busch, Jan; Blankemeyer, Sebastian; Raatz, Annika; Nyhuis, Peter (Amsterdam : Elsevier B.V., 2016)
    An active aerodynamic feeding system developed at the IFA offers a large potential regarding output rate, reliability and neutrality towards part geometries. In this paper, the procedure of a genetic algorithm's into the ...
  • Importance of the vane exit Mach number on the axial clearance-related losses 
    Grönman, Aki; Biester, Marc H.-O.; Turunen-Saaresti, Teemu; Jaatinen-Värri, Ahti; Backman, Jari; Seume, Jörg R. (London : SAGE Publications Ltd., 2016)
    More efficient and physically smaller axial turbine designs are promoted to lower emissions and increase revenue. The physical size and the weight of the axial turbine can be minimised by adjusting the distance between ...
  • Model tests on the control behaviour of a test air supply system in open or closed-loop operation 
    De Buhr, L.; Fleige, H.; Seume, J. (Bristol : Institute of Physics Publishing, 2018)
    The Leibniz Universität Hannover is currently establishing a new mechanical engineering campus which includes a new research building "Dynamics of Energy Conversion" (DEW). This building provides a large compressor station ...
  • Results of the research project AssiSt 
    Kühn, Timo; Altmikus, Andree; Daboul, Hussam; Radi, Alexander; Raasch, Siegfried; Knigge, Christoph; Böske, Lennart; Schwarz, Thorsten; Heister, Christoph; Langer-Möller, Annika; Lutz, Thorsten; Weihing, Pascal; Schulz, Christoph; Thiemeier, Jakob; Mockett, Charles; Fuchs, Marian; Thiele, Frank (Bristol : Institute of Physics Publishing, 2018)
    This article gives an overview of the results of the wind energy research project AssiSt. Results of the four work packages include flow in complex terrain, wind energy converters (WEC) in complex terrain subject to ...
  • A structural design concept for a multi-shell blended wing body with laminar flow control 
    Bishara, Majeed; Horst, Peter; Madhusoodanan, Hinesh; Brod, Martin; Daum, Benedikt; Rolfes, Raimund (Basel : MDPI AG, 2018)
    Static and fatigue analyses are presented for a new blended wing body (BWB) fuselage concept considering laminar flow control (LFC) by boundary layer suction in order to reduce the aerodynamic drag. BWB aircraft design ...
  • Water tank experiments on stratified flow over double mountain-shaped obstacles at high-reynolds number 
    Stiperski, Ivana; Serafin, Stefano; Paci, Alexandre; Ágústsson, Halfdan; Belleudy, Anne; Calmer, Radiance; Horvath, Kristian; Knigge, Christoph; Sachsperger, Johannes; Strauss, Luke; Grubišíc, Vanda (Basel : MDPI AG, 2017)
