A comparison of physical and numerical modeling of homogenous isotropic propeller blades
Savio, Luca; Sileo, Lucia; Ås, Sigmund Kyrre (Journal article; Peer reviewed, 2020)Results of the fluid-structure co-simulations that were carried out as part of the FleksProp project are presented. The FleksProp project aims to establish better design procedures that take into account the hydroelastic ... -
A computational iterative design method for bend-twist deformation in composite ship propeller blades for thrusters
Rokvam, Sondre Østli; Vedvik, Nils-Petter; Mark, Lukas; Rømcke, Eivind; Ølnes, Jon; Savio, Luca; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)This study investigates the feasibility of utilising common composite material layup techniques in ship propeller blade design to achieve an automatic pitch adjustment through bending-induced twist deformation. A comprehensive ... -
Designing Composite Adaptive Propeller Blades with Passive Bend–Twist Deformation for Periodic-Load Variations Using Multiple Design Concepts
Rokvam, Sondre Østli; Vedvik, Nils-Petter; Savio, Luca; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2023)Four plausible design concepts are applied together to investigate composite bend–twist propeller-blade designs that show high twisting per bending deflection. The design concepts are first explained on a simplified blade ... -
Examination of Complex High Reynolds Number Wall-Bounded Adverse Pressure Gradient Flow Using Advanced Measuring Techniques
Jenssen, Yngve Lilleeng (Master thesis, 2021)Denne masteroppgaven er den del av et pågående NATO STO (Science and Technology Organisation) samarbeidsprosjekt mellom Virginia Tech, NTNU/SINTEF Ocean og University of Toronto. Målet med dette prosjektet er å lage CFD ... -
Experimental and numerical investigations on wave profiles and ventilation on a surface-piercing hydrofoil
Solheim Høstmark,; Elisa (Master thesis, 2021)En serie eksperimenter ble gjennomført på to separate overflate-brytende hydrofoiler med Froude tall og angrepsvinkler som hovedparametrene. En bred foil med maksimum tykkelse, t = 120mm, der bølgeprofilene ble undersøkt ... -
Experimental Testing of Cabrinha Fusion X1300 Foilkit in Towing Tank
Røkenes, Heidi (Master thesis, 2021)Denne oppgaven dekker en experimentell studie av et Cabrinha Fusion X1300 foil kit, som benyttes til kiting og surfing. Ettersom det er en eksperimentell oppgave, inneholder den planlegging av eksperiment og testprogram, ... -
Experimental verification of the elastic response in a numeric model of a composite propeller blade with bend twist deformation
Rokvam, Sondre Østli; Vedvik, Nils Petter; Mark, Lukas; Rømcke, Eivind; Ølnes, Jon; Savio, Luca; Echtermeyer, Andreas (Journal article; Peer reviewed, 2021) -
Hydrodynamic Aspects of Sail-Assisted Merchant Vessels
Kramer, Jarle Vinje (Doctoral theses at NTNU;2022:190, Doctoral thesis, 2022)Modern sail technology is a potential solution for reducing the fuel consumption for merchant ships. This can be used to either reduce the emission of greenhouse gasses with conventional fuels, or the cost related to ... -
Hydrodynamic design of an affordable USV
Brodin, Hermann (Master thesis, 2020)Denne masteroppgaven presenter et arbeid som er gjennomført for å designe et rimelig priset ubemannet overflatefartøy. Oppgaven er delt inn i fire steg hvorav den første er å kombinere potensialteori, empiriske modeller ... -
Identification and Analysis of Full Scale Ventilation Events
Savio, Luca; Steen, Sverre (Journal article; Peer reviewed, 2012)The present paper deals with propeller ventilation in full scale. The paper is based on full scale monitoring data from an offshore supply ship during normal operation. The data was collected by the on-line monitoring ... -
Predicting thrust loss of ship propellers due to ventilation and out-of-water effect
Kozlowska, Anna Maria; Savio, Luca; Steen, Sverre (Journal article; Peer reviewed, 2017)This paper presents a propeller ventilation model that is tuned on experiments performed in open water condition in a towing tank. The main purpose of performing the experiments was to obtain more data at higher advance ... -
Time Domain Modeling of Propeller Forces due to Ventilation in Static and Dynamic Conditions
Kozlowska, Anna Maria; Dalheim, Øyvind Øksnes; Savio, Luca; Steen, Sverre (Journal article; Peer reviewed, 2020)This paper presents experimental and theoretical studies on the dynamic effect on the propeller loading due to ventilation by using a simulation model that generates a time domain solution for propeller forces in varying ... -
Wall Modeled Large Eddy Simulation of Viscous Flow on the BeVERLI Hill Geometry
Engan, Lars (Master thesis, 2021)I denne masteroppgaven har vegg-modellert LES blitt brukt til å simulere den viskøse strømningen over BeVERLI hill geometrien. BeVERLI hill er en veggmontert «bump» som blir brukt i valideringsstudier av turbulente separerte ...
