• Acoustic-Convective Interference in Transfer Functions of Methane/Hydrogen and Pure Hydrogen Flames 

      Æsøy, Eirik; Aguilar, Jose; Bothien, Mirko R.; Worth, Nicholas; Dawson, James (Peer reviewed; Journal article, 2021)
      We investigate the occurrence and source of modulations in the gain and phase of flame transfer functions (FTF) measured in perfectly premixed, bluff body stabilized CH4=H2 and pure H2 flames. The modulations are shown to ...
    • The response of an axisymmetric jet placed at various positions in a standing wave 

      Æsøy, Eirik; Aguilar, Jose; Worth, Nicholas; Dawson, James (Peer reviewed; Journal article, 2021)
      The hydrodynamic response of an axisymmetric jet placed at various positions in a standing wave oriented normally to the jet is investigated. At the velocity and pressure nodes the axisymmetric (m=0) and first azimuthal ...
    • Scaling and prediction of transfer functions in lean premixed H2/CH4-flames 

      Æsøy, Eirik; Aguilar, Jose; Wiseman, Samuel; Bothien, Mirko R.; Worth, Nicholas; Dawson, James (Journal article, 2020)
      Features of the flame transfer function (FTF) are characterized for turbulent, non-swirled, bluff body stabilized “M” flames for different hydrogen and methane blends including pure hydrogen flames. An increase in the ...
