    • Governing physics of shallow and deep subsea gas release 

      Olsen, Jan Erik; Skjetne, Paal (SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)
      A modelling concept for studying the resulting bubble plume from a subsea gas release is presented. Simulation results show good consistency with available experimental data. The modelling concept is applied to assess the ...

    • Performance evaluation of a complete Lagrangian KTGF approach for dilute granular flow modelling 

      Cloete, Schalk; Johansen, Stein Tore; Amini, Shahriar (Peer reviewed; Journal article, 2012)
      Finely resolved gas–solid flow simulations were carried out using an improved Lagrangian method known as the dense discrete phase model (DDPM). The DDPM differs from the traditional Eulerian two fluid model (TFM) approach ...

    • VLES turbulence model for an Eulerian–Lagrangian modeling concept for bubble plumes 

      Olsen, Jan Erik; Skjetne, Paal; Johansen, Stein Tore (Peer reviewed; Journal article, 2017)
      Traditional Reynolds-averaged Navier–Stokes (RANS) approaches to turbulence modeling, such as the k-ϵ model, have some well-known shortcomings when modeling transient flow phenomena. To mitigate this, a filtered URANS model ...
