1. CFD Predictions Including Verification and Validation of Hydrodynamic Forces and Moments on Ships in Restricted Waters
Sammanfattning : The evaluation of ship manoeuvrability is of significance at the initial design stage, as inappropriate manoeuvring performance may result in unstable ship motion, difficulties in steering and even marine accidents. Restricted waters, with the presence of solid boundaries of the flow field, such as a shallow seabed below the hull, a side bank in the vicinity of the hull or another hull nearby, complicate the flow field and introduce an influence on hydrodynamic forces and moments acting on the hull.

3. Simulation model of a ship’s energy performance and transportation costs
Sammanfattning : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.

4. Loads and responses for planing craft in waves
Sammanfattning : Experimental and numerical analysis of loads and responses for planing craft in waves is considered. Extensive experiments have been performed on a planing craft, in full-scale as well as in model scale. The test set-ups and significant results are reviewed. LÄS MER
