SEAKEEPING PERFORMANCE OF A HYDROFOIL IN WAVES USING CFD APPROACH

Universiti Malaysia Terengganu Journal of Undergraduate Research, 2021
Hydrofoil usually experiences high resistance and excessive vertical motions (heave and pitch) that may affect the passenger’s comfort due to the harsh environmental condition. Therefore, it is necessary to investigate seakeeping performance of a hydrofoil ship in waves due to the presence of a complex hydrodynamic phenomenon. To achieve this objective,

Fatigue Strength Assessment of Trimaran Cross‐Deck Structure Based on Spectral and Simplified Fatigue Method

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In order to investigate the fatigue behaviour of trimaran cross‐deck structural details, the spectral and simplified fatigue analysis approaches are proposed. In spectral fatigue approach, three‐dimensional (3D) linear potential flow theory and global FE analysis are used for wave loads and stress transfer functions calculation; the stochastic spectral

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Sensitivity Analysis Based on Polynomial Chaos Expansions and Its Application in Ship Uncertainty‐Based Design Optimization

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In order to truly reflect the ship performance under the influence of uncertainties, uncertainty‐based design optimization (UDO) for ships that fully considers various uncertainties in the early stage of design has gradually received more and more attention.

Establishment of the Unified Maneuvering and Seakeeping Dynamic Model for Submarines Moving in Horizontal Plane near Free Surface

Journal of Marine Science and Engineering
When a submarine moves near the free surface, the lift and drag characteristics that act on it are different compared to when in deep water; for example, waves on the free surface cause submarine motions that are not seen in deep water conditions and ...
