  • Anisotropy and shear-layer edge dynamics of statistically unsteady, stratified turbulence 
    Wingstedt, Emma My Maria; Fossum, Hannibal Eie; Reif, Bjørn Anders Pettersson; Werne, Joseph (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Direct numerical simulation data of an evolving Kelvin-Helmholtz instability have been analyzed in order to characterize the dynamic and kinematic response of shear-generated turbulent flow to imposed stable stratification. ...
  • Computational modeling of stably stratified, turbulent shear flows 
    Fossum, Hannibal Eie (Doctoral thesis / Doktoravhandling, 2015)
    The present thesis is motivated by the desire to understand and to predict the effects of stable stratification on turbulent flow and passive scalar dispersion. A methodology which enables the simulation of stably stratified, ...
  • A model for the viscous dissipation rate in stably stratified, sheared turbulence 
    Fossum, Hannibal Eie; Wingstedt, Emma My Maria; Reif, Bjørn Anders Pettersson (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    [1] A model for the turbulence dissipation rate in stably stratified shear turbulence is developed and validated. The functional dependence of the model is derived from first principles and it represents a conceptually new ...
  • Predicting Particle Deposition in the Human Airways with RANS Turbulence Modeling 
    Fossum, Hannibal Eie (Master thesis / Masteroppgave, 2009)
    Particle deposition in the lungs have so far been modeled mainly with the assumption of laminar flow. In the present study, several Reynolds-Averaged Navier-Stokes (RANS) turbulence models are used to simulate the airflow ...
