In this paper, several commonly used vortex identification methods for marine
hydrodynamics are revisited. In order to extract and analyse the vortical structures in marine …

The crowded waterways and worse maneuverability of large ships could cause more
collision accidents. Therefore, it is necessary to study stopping ability of ships to ensure the …

The present study aims to investigate the scale effects of the open water propeller
performance using computational fluid dynamics (CFD). The results are presented for the …

In this paper, the self-propelled characteristics of the benchmark ONRT hull were studied
experimentally at both Froude numbers, Fr= 0.20 and Fr= 0.30. The assessments were …

This paper proposes the modification of the propulsion system of the surface ship ONRT and
the optimization strategy for the stern propulsion system of the modified ship. Specifically …

In the present work, ship propulsion performance at different trim angles are investigated.
CFD method with dynamic overset grid technique is used to direct simulate the free running …

The interactions between a ship's hull and podded propulsors differ significantly from
traditional hullpropeller interactions, leading to distinct influences on self-propulsion …

The scope of this work is to present and discuss the results obtained from simulating the bow
wave generated by a ship advancing in calm water. A rectangular flat plate is used instead …

The cutter suction dredger (CSD) is a special type of engineering ship. It has normally a
large breath-to-draught ratio, and openings are always necessary on the hull to install the …

So far, self-propulsion simulation using fully discretized approach by modelling all moving
components, especially for the rotating propellers, is very time consuming. It is very …
