• Characterizing the surface texture of a dense suspension undergoing dynamic jamming 

      Rømcke, Olav; Peters, Ivo R.; Hearst, Robert Jason (Peer reviewed; Journal article, 2021)
      Measurements of the surface velocity and surface texture of a freely propagating shear jamming front in a dense suspension are compared. The velocity fields are captured with particle image velocimetry (PIV), while the ...
    • Colliding jamming fronts in a dense suspension 

      Rømcke, Olav (Doctoral theses at NTNU;2021:366, Doctoral thesis, 2021)
      Mixtures of liquids and solid particles, known as suspensions, are a quite common material both in natural and industrial processes. For a high concentration of particles, some of these mixtures exhibit a quite remarkable ...
    • Collision of dynamic jamming fronts in a dense suspension 

      Peters, Ivo R.; Hearst, R. Jason; Rømcke, Olav (Peer reviewed; Journal article, 2021)
      Dynamic jamming is a phenomenon whereby a dense suspension switches from a fluidlike to a solidlike state when subjected to sufficient stress and deformation. Large enough systems show that this transition is accompanied ...
    • Experimental study of the impact of surface waves on turbulent flows 

      Djupesland, Johannes (Master thesis, 2023)
      Denne avhandlingen er en eksperimentell studie som undersøker samspillet mellom overflatebølger og turbulens, og det er en konseptbevis-studie som tester mulighetene for denne typen eksperimenter i dette laboratoriet. ...
    • Experimental study of the mutual interactions between waves and tailored turbulence 

      Smeltzer, Benjamin Keeler; Rømcke, Olav; Hearst, R. Jason; Ellingsen, Simen Andreas Ådnøy (Peer reviewed; Journal article, 2023)
      When surface waves interact with ambient turbulence, the two affect each other mutually. Turbulent eddies get redirected, intensified and periodically stretched and compressed, while the waves suffer directional scattering. ...
    • Getting jammed in all directions: Dynamic shear jamming around a cylinder towed through a dense suspension 

      Rømcke, Olav; Peters, Ivo R.; Hearst, Robert Jason (Peer reviewed; Journal article, 2021)
      Experimental results of towing a cylinder through a dense suspension of cornstarch and sucrose-water are presented. Focus is placed on the jamming fronts that exist in such systems. The literature has concentrated on the ...
    • The impact of upstream turbulence on a plane jet 

      Kamruzzaman, Md; Rømcke, Olav; Hearst, R. Jason (Peer reviewed; Journal article, 2021)
      The influence of upstream turbulence on the flow produced by a plane jet is investigated experimentally with hot-wire anemometry and smoke flow visualisation. An innovative active grid, where each wing can be independently ...
    • Numerical Simulation of Solidifying Flow - Numerisk simuleringing av størking 

      Rømcke, Olav (Master thesis, 2018)
      This thesis consists of deriving and testing a numerical model for convection dominated solid-liquid phase transitions. Two scientific articles represents the main body of the thesis, but a short documentation of the work ...
    • The role of Lagrangian drift in the geometry, kinematics and dynamics of surface waves 

      Pizzo, Nick; Lenain, Luc; Rømcke, Olav; Ellingsen, Simen Andreas Ådnøy; Smeltzer, Benjamin Keeler (Peer reviewed; Journal article, 2023)
      The role of the Lagrangian mean flow, or drift, in modulating the geometry, kinematics and dynamics of rotational and irrotational deep-water surface gravity waves is examined. A general theory for permanent progressive ...
