• Model Order Reduction Technique Applied on Harmonic Analysis of a Submerged Vibrating Blade 

      Tengs, Erik Os; Charrassier, Flora; Storli, Pål-Tore Selbo; Holst, Martin (Journal article; Peer reviewed, 2019)
      As part of an ongoing study into hydropower runner failure, a submerged, vibrating blade is investigated both experimentally and numerically. The numerical simulations performed are fully coupled acoustic-structural ...
    • Numerical simulation of a droplet-film collision using a phase-field approach 

      Tengs, Erik Os (Master thesis, 2016)
      Computational Fluid Dynamics is the science of solving the governing equations of fluid motion numerically. Simulating multiphase flow has traditionally been difficult, due to non-uniform fluid properties and challenges ...
    • Optimization procedure for variable speed turbine design 

      Tengs, Erik Os; Storli, Pål-Tore Selbo; Holst, Martin (Journal article; Peer reviewed, 2018)
      This article outlines a design procedure for variable speed Francis turbines using optimization software. A fully parameterized turbine design procedure is implemented in MATLAB. ANSYS CFX is used to create hill diagrams ...
