(2011)
Conference report
Open AccessThis article deals with diagnostic technology of naval gas turbine engines based on exhaust temperature measurements. It contains a detailed discussion devoted unsteady thermal-flow processes worked out within the ... -
Ship electric propulsion: analyses through modeling and simulation
(2011)
Conference report
Open AccessElectric propulsion has been applied to ships via DC motors for more than a century offering effective manoeuvrability, precise and smooth speed control, reduced space machinery, low noise and low pollution rates. The ... -
Feasibility of an innovative wing mast for a sustainable use in fishing boats, tankers and cargo ships
(2011)
Conference report
Open AccessThe purpose of this paper is to demonstrate the feasibility of an innovative project of multi-role fishing boat based on a SWATH catamaran architecture, high efficiency propellers and innovative wind sail auxiliary ... -
A numerical and experimental study on the hydrodynamic of a catamaran varying the demihull separation
(2011)
Conference report
Open AccessA complementary experimental and numerical study of the interference effect for a fast catamaran is presented. Resistance, sinkage and trim are collected by towing tank experiments for Froude number in the range from 0.2 ... -
Anisotropic mesh refinement in ship flow simulation with free surface
(2011)
Conference report
Open AccessFor the simulation of water flow with waves, grid refinement must be anisotropic to limit the total grid size. For these flows, the grid has to be refined at the water surface, to resolve the conservation law which ... -
Prediction of the transom flow regime with viscous free surface computations
(2011)
Conference report
Open AccessA steady free-surface fitting RANS method is used to accurately and efficiently compute the flow near a ship‟s transom. The chosen block topology is very well suited for the prediction of such flows: viscous free-surface ... -
Adjoint aftship re-design for wake optimisation under the influence
(2011)
Conference report
Open AccessThe paper outlines means for an efficient RANS-based hull-design optimisation process. The adjoint-based wake design method previously applied to an unpropelled ship [5] was now extended to optimise a ship hull in ... -
Fast robust design optimisation methods applied to ship hydrodynamics
(2011)
Conference report
Open AccessThis paper describes the benefits of fast multi-objective design optimisation methods applied to ship hydrodynamics and coupled to Computational Fluid Dynamics models. -
Large eddy simulation of the flow past the DTMB5415 surface combatant hull with and without bilge keels
(2011)
Conference report
Open AccessThe flow around the DTMB5415 surface combatant hull with and without bilge keels is studied numerically by the use of a Large Eddy Simulation (LES) method. The main purpose for bilge keels is to reduce roll motions when ... -
On the application of wall functions in ship viscous flows
(2011)
Conference report
Open AccessThis paper presents a numerical study on quantifying the effect of wall function boundary conditions on the calculation of ship viscous flows based on the RANS equations at model and full scale Reynolds numbers. Grid ... -
Use of RANS for analysis of a high-speed sealift concept vessel
(2011)
Conference report
Open AccessTo better understand performance for high speed surface ships, Reynolds Averaged Navier-Stokes (RANS) calculations are performed on the Joint High Speed Sealift (JHSS), which is a monohull concept with four waterjets. ...
