Evaluation of three different foil-strut junction designs for a hydrofoil vessel
Tomasgaard, Hermann (Master thesis, 2023)Selve sammenkoblingen mellom "strut" og "foil" i "hydrofoilen" har stor betydning for den totale motstanden til hydrofoil-systemer. Dette hovedsakelig på grunn av inteferensmotstand som forårsakes av det møtende grensesjiktet ... -
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 ... -
Sail-induced resistance on a wind-powered cargo ship
Kramer, Jarle Vinje; Steen, Sverre (Peer reviewed; Journal article, 2022)This article explores the added resistance due to side forces from wingsails, called the sail-induced resistance. A cargo ship is tested with varying speed, appendages, number of sails, and control algorithms for the sails. ... -
Simplified test program for hydrodynamic CFD simulations of wind-powered cargo ships
Kramer, Jarle Vinje; Steen, Sverre (Journal article; Peer reviewed, 2022)Four practical simplifications for modeling the hydrodynamic properties of a wind-powered cargo ship with CFD and a route simulation model is evaluated. We first test how much the drift-induced hull forces are dependent ...
