  • Combustion models for shock-induced cloud ignition of aluminium particles using smoothed particle hydrodynamics 
    Omang, Marianne Gjestvold; Hauge, K.O.; Trulsen, Jan Karsten (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract The present work is a numerical follow-up on our published experimental paper on shock ignition of aluminium particle clouds in the low-temperature regime. The in-house multi-phase regularized smoothed particle ...
  • Computational analysis of shock-induced flow through stationary particle clouds 
    Osnes, Andreas Nygård; Vartdal, Magnus; Omang, Marianne Gjestvold; Reif, Bjørn Anders Pettersson (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    We investigate the shock-induced flow through random particle arrays using particle-resolved Large Eddy Simulations for different incident shock wave Mach numbers, particle volume fractions and particle sizes. We analyze ...
  • Particle-resolved simulations of shock-induced flow through particle clouds at different Reynolds numbers 
    Osnes, Andreas Nygård; Vartdal, Magnus; Omang, Marianne Gjestvold; Reif, Bjørn Anders Pettersson (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    This study investigates the Reynolds-number dependence of shock-induced flow through stationary particle clouds at 10% volume fraction, using ensemble-averaged results from three-dimensional particle-resolved large eddy ...
  • Shock ignition of aluminium particle clouds in the low-temperature regime 
    Omang, Marianne Gjestvold; Hauge, Knut Ove (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    In this paper, we present results from spontaneous ignition of aluminium particle clouds in a series of shock tube experiments. For all experiments, the shock propagates along a narrow pile of 40-μm aluminium particles. ...
