  • 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 ...
  • Relationship between frequencies of pressure oscillations and rotor speed under rotating stall 
    Levy, Y.; Pismenny, J.; Reissner, A.; Riess, W. (Berlin : De Gruyter, 2002)
    The correlation between the frequencies of pressure oscillation ωosc and the rotor speed (frequencies of rotor rotation ωRR) under established rotating stall were determined by three methods: directly from the time diagram ...
  • 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)
    In this article,we present an overviewof theHyIV-CNRS-SecORo (Hydralab IV-CNRS-Secondary Orography and Rotors Experiments) laboratory experiments carried out in the CNRM (Centre National de Recherches Météorologiques) large ...
