The Effect of Rectangular Confinement Aspect Ratio On the Flame Transfer Function of a Turbulent Swirling Flame
Ånestad, Aksel; Ahn, Byeonguk; Nygård, Håkon Tormodsen; Worth, Nicholas (Peer reviewed; Journal article, 2022)The flame transfer function (FTF) has been experimentally investigated for a premixed, turbulent and highly swirled flame in rectangular enclosures with varying aspect ratio. A range of equivalence ratios and inlet bulk ... -
Mitigating Thermoacoustic Instabilities in Premixed Hydrogen Flames using Axial Staging
Ånestad, Aksel; Æsøy, Eirik; Dawson, James; Worth, Nicholas Alexander (Journal article; Peer reviewed, 2024)In this paper we demonstrate how axial staging can be utilised to mitigate thermoacoustic instabilities in a combustion system by flame redistribution. This is achieved by moving flow to a second stage flame while keeping ... -
The Effect of Nonuniform Wall Spacing on the Flame Transfer Function of a Turbulent Swirling Flame
Ånestad, Aksel (Master thesis, 2021)Eksperimentelle undersøkelser har blitt gjennomført for å studere effekten av varierende veggavstand på flammetransferfunksjonen til en turbulent, virvlet og forblandet flamme i et ikke-uniformt brennkammer. For å variere ...
