A Semi-Analytical Method for Calculating the Hydrodynamic Force on Perforated Plates in Oscillating Flow
Mentzoni, Fredrik; Kristiansen, Trygve (Chapter, 2019)A two-dimensional numerical analysis on the hydrodynamic force of perforated plates in oscillating flow is presented, and a new semi-analytical force model is proposed. Plates with ten different perforation ratios, τ, from ... -
An Experimental and Numerical Study of Added Mass and Damping for Side by Side Plates in Oscillating Flow
Solaas, Frøydis; Mentzoni, Fredrik; Abrahamsen-Prsic, Mia; Kristiansen, Trygve (Chapter, 2019)Forced harmonic oscillations of seven configurations consisting of horizontal side by side plate elements are performed experimentally and numerically. The configurations are oscillated in vertical direction and represent ... -
Experimental Investigation of Porous Structures in Splash Zone
Gupta, Prateek (Master thesis, 2018)First, the KC number (or porous KC number) varying hydrodynamic coefficients for porous plates are determined from forced oscillations in deep water. Then water-entry drag coefficient is determined from the force impulse ... -
Hydrodynamic Coefficients of Simplified Subsea Structures
Mentzoni, Fredrik; Abrahamsen-Prsic, Mia; Kristiansen, Trygve (Chapter, 2018)Simplified two-dimensional models, representing components of complex subsea structures, are experimentally investigated. Individual as well as combinations of components in different configurations are tested, in order ... -
Hydrodynamic Loads on Complex Structures in the Wave Zone
Mentzoni, Fredrik (Doctoral theses at NTNU;2020:159, Doctoral thesis, 2020)The hydrodynamic loads on simplified structures relevant for deployment of subsea modules are studied in a two-dimensional setting. Experimental investigations and numerical simulations are performed. In the experiments, ... -
Numerical modeling of perforated plates in oscillating flow
Mentzoni, Fredrik; Kristiansen, Trygve (Journal article; Peer reviewed, 2019)Perforated plates, relevant for several marine applications, are experimentally and numerically investigated. The numerical investigations are performed using a presently developed Navier–Stokes solver. Several comparison ... -
Numerical modeling of turbulence above helidecks
Mentzoni, Fredrik (Master thesis, 2014)New regulations in the second edition of NORSOK Standard C-004, released in May 2013, require the use of a Reynolds stress transport model for numerical simulations of turbulence above helidecks on the Norwegian continental ... -
Two-dimensional experimental and numerical investigations of parallel perforated plates in oscillating and orbital flows
Mentzoni, Fredrik; Kristiansen, Trygve (Peer reviewed; Journal article, 2020)The hydrodynamic loads on two-dimensional perforated plates are investigated experimentally and numerically. Two parallel plate configurations, consisting of an upper perforated plate and a lower perforated plate, are ... -
Two-dimensional experimental and numerical investigations of perforated plates in oscillating flow, orbital flow and incident waves
Mentzoni, Fredrik; Kristiansen, Trygve (Peer reviewed; Journal article, 2020)The hydrodynamic loads on two-dimensional perforated plates are investigated experimentally and numerically. Two single perforated plate configurations, consisting of rows of either circular or square cylinders, are studied. ...
