A 2D+t approach for the transverse viscous loads in a modular maneuvering model
Rabliås, Øyvind; Kristiansen, Trygve (Peer reviewed; Journal article, 2021)The importance of the transverse viscous loads, in a modular maneuvering model, is investigated. A method to estimate steady sectional drag coefficients is first presented. A 2D+t approach, which accounts for forward-speed ... -
Development of a new Navier-Stokes Solver using a Generalized HPC method for the Pressure Poisson Equation
Rabliås, Øyvind (Master thesis, 2016)The computational cost of solving the Navier-Stokes equations numerically is too high for most full-scale applications, especially within the marine field. Many marine structures are defined as large volume structures. For ... -
Numerical and Experimental Studies of Maneuvering in Regular and Irregular Waves
Rabliås, Øyvind (Doctoral theses at NTNU;2022:168, Doctoral thesis, 2022)The present work is a numerical and experimental study on maneuvering in regular and irregular waves of the Duisburg Test Case (DTC), a container ship with block coefficient CB = 0:661. Two test campaigns of free-running ... -
A rational model for maneuvering in irregular waves with the effect of waves on the propeller and rudder inflow taken into account
Rabliås, Øyvind; Kristiansen, Trygve (Peer reviewed; Journal article, 2022)A modular model for maneuvering in regular and irregular waves is presented. A new model is presented for the y-component of the rudder inflow. Moreover, an efficient time-domain method for estimation of slowly varying ...
