    • A New Level Set Numerical Wave Tank with Improved Density Interpolation for Complex Wave Hydrodynamics 

      Bihs, Hans; Kamath, Arun; Alagan Chella, Mayilvahanan; Aggarwal, Ankit; Arntsen, Øivind Asgeir (Journal article; Peer reviewed, 2016)
      A new three-dimensional numerical wave tank is developed for the calculation of wave propagation and wave hydrodynamics by solving the incompressible Navier–Stokes equations. The free surface is modeled with the level set ...

    • Calculation of the interface curvature and normal vector with the level-set method 

      Lervåg, Karl Yngve; Müller, Bernhard; Munkejord, Svend Tollak (Journal article, 2013)
      This article addresses the use of the level-set method for capturing the interface between two fluids. One of the advantages of the level-set method is that the curvature and the normal vector of the interface can be readily ...

    • Gas cavity-body interactions: Efficient numerical solution 

      Colicchio, Giuseppina; Greco, Marilena; Faltinsen, Odd Magnus; Brocchini, Maurizio (Journal article; Peer reviewed, 2015)
      The paper investigates the interactions occurring between a gas cavity, the surrounding liquid and the nearby structures. In more detail, focus is in the characterization of the various dynamical phases (e.g. “acoustic ...

    • HLLC-type methods for compressible two-phase flow in ducts with discontinuous area changes 

      Log, Alexandra Metallinou; Munkejord, Svend Tollak; Hammer, Morten (Peer reviewed; Journal article, 2021)
      In this work, the Harten-Lax-van Leer Contact (HLLC) approximate Riemann solver is extended to two-phase flow through ducts with discontinuous cross-sections. Two main strategies are explored regarding the treatment of the ...

    • Immersed boundary method for viscous compressible flows around moving bodies 

      Khalili, Mohammadtaghi; Larsson, Martin; Müller, Bernhard (Journal article; Peer reviewed, 2018)
      A ghost-point immersed boundary method for the compressible Navier–Stokes equations with moving boundaries on fixed Cartesian grids is devised by employing high order summation-by-parts (SBP) difference operators. The ...

    • Influence of spanwise no-slip boundary conditions on the flow around a cylinder 

      Strandenes, Håkon; Pettersen, Bjørnar; Andersson, Helge Ingolf; Manhart, Michael (Journal article; Peer reviewed, 2017)
      First we present high resolution large eddy simulations (LES) for the flow past a circular cylinder at Reynolds number 3900 to prove the quality of the simulations. A thorough grid convergence study is presented, and the ...

    • Large-eddy simulations of the flow over a semi-circular cylinder at Re = 50000 

      Lysenko, Dmitry A; Donskov, Mark; Ertesvåg, Ivar Ståle (Journal article, 2021)
      Large-eddy simulations (LES) of the flow over a semi-circular cylinder at a diameter-based Reynolds number 50000 and zero angle of attack are presented. In comparison with the prominent benchmark flows past circular and ...

    • Rankine-Hugoniot-Riemann solver for steady multidimensional conservation laws with source terms 

      Lund, Halvor; Müller, Florian; Müller, Bernhard; Jenny, Patrick (Journal article; Peer reviewed, 2014)
      The Rankine-Hugoniot-Riemann (RHR) solver has been designed to solve steady multidimensional conservation laws with source terms. The solver uses a novel way of incorporating cross fluxes as source terms. The combined ...

    • Using ALE-VMS to compute aerodynamic derivatives of bridge sections 

      Helgedagsrud, Tore Andreas; Bazilevs, Yuri; Korobenko, Artem; Mathisen, Kjell Magne; Øiseth, Ole (Journal article; Peer reviewed, 2018)
      Aeroelastic analysis is a major task in the design of long-span bridges, and recent developments in computer power and technology have made Computational Fluid Dynamics (CFD) an important supplement to wind tunnel experiments. ...
