• Diffuse Back-Illuminated Extinction Imaging of Soot: Effects of Beam Steering and Flame Luminosity 

      Bjørgen, Karl Oskar Pires; Emberson, David; Løvås, Terese (Journal article; Peer reviewed, 2019)
      This study presents diagnostic development of diffuse backilluminated extinction imaging of soot. The method provides high temporal and spatial resolution of the line-of-sight optical density of soot (KL) in compression-ignited ...
    • Experimental Investigations of an Icing Protection System for UAVs 

      Hann, Richard; Borup, Kasper Trolle; Zolich, Artur Piotr; Sørensen, Kim Lynge; Vestad, Håvard Nitter; Steinert, Martin; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)
      UAV icing is a severe challenge that has only recently shifted into the focus of research. Today, there are no mature icing mitigation technologies for UAVs, except for the largest fixed-wing drones. We are working on the ...

    • On Soot Sampling: Considerations when Sampling for TEM Imaging and Differential Mobility Spectrometer 

      Emberson, David; Rohani, Behzad; Wang, Liang; Sæterli, Ragnhild; Løvås, Terese (Journal article; Peer reviewed, 2019)
      Particulate matter (PM) has been sampled from a compression ignition engine using a differential mobility spectrometer (Cambustion DMS 500) and for imaging in a transmission electron microscope (TEM) with the aim of coupling ...
    • UAV Icing: Ice Accretion Experiments and Validation 

      Hann, Richard (Journal article; Peer reviewed, 2019)
      Atmospheric icing is a key challenge to the operational envelope of medium-sized fixed-wing UAVs. Today, several numeric icing codes exist, that all have been developed for general aviation applications. UAVs with wingspans ...
