A monolithic finite element formulation for the hydroelastic analysis of very large floating structures

International Journal for Numerical Methods in Engineering, Volume 124, Issue 3, Page 714-751, 15 February 2023., 2023
Abstract In this work we present a novel monolithic Finite Element method for the hydroelastic analysis of very large floating structures (VLFS) with arbitrary shapes that is stable, energy conserving, and overcomes the need of an iterative algorithm. The new formulation enables a fully monolithic solution of the linear free‐surface flow, described by ...

Fuzzy Airflow‐Based Active Structural Control of Integrated Oscillating Water Columns for the Enhancement of Floating Offshore Wind Turbine Stabilization

International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023
This paper presents the modeling and stabilization of a floating offshore wind turbine (FOWT) using oscillating water columns (OWCs) as active structural control. The novel concept of this work is to design a new FOWT platform using the ITI Energy barge with incorporated OWCs at opposite sides of the tower, in order to alleviate the unwanted system ...

Dynamic Response Simulation of the Slope Triggered by Fluctuating Pressure during High Dam Flood Discharge

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
The problem of slope vibration induced by flood discharge of high dams cannot be ignored. In this paper, this problem is simplified to be the relationship among the fluctuating pressures, the inherent properties of the slope system, and its dynamic responses.

Numerical Researches of Rectangular Barge in Variable Bathymetry Based on Boussinesq‐Step Method

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
Wave responses of the rectangular barge in variable bathymetry are investigated by combining the Boussinesq‐type equations and the step method. The highly accurate Boussinesq‐type equations in terms of velocity potential are adopted for simulating the evolution of waves along the inclined beach. Hydrodynamic coefficients of a rectangular barge floating

Modal Investigation on a Large‐Scale Containership Model for Hydroelastic Analysis

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
A 20,000 TEU containership with an overall length of about 400 m is designed as a target ship to investigate ship hydroelastic characteristics in the joint industry project (JIP) of CSSRC‐20,000 TEU. A set of systematic model tests are carried out in the seakeeping wave basin of CSSRC.

Numerical Study on the Water Entry Impact Forces of an Air‐Launched Underwater Glider under Wave Conditions

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
In this study, the water entry of an air‐launched underwater glider under wave conditions is numerically simulated by the computational fluid dynamics method. The numerical model is validated by the comparison of nondimensional water entry impact force with published experimental and numerical results.

A Fully Coupled Time‐Domain BEM‐FEM Method for the Prediction of Symmetric Hydroelastic Responses of Ships with Forward Speed

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
This paper presents a direct time‐domain method for the prediction of symmetric hydroelastic responses of ships progressing with forward speed in small amplitude waves. A transient time‐domain free surface Green function is used for the idealisation of the seakeeping problem using an Earth fixed coordinate system.

Interaction of a Flexural-Gravity Wave with a Vertical Rigid Plate Built in a Floating Elastic Plate

Journal of Marine Science and Engineering, 2023
The linear two-dimensional problem of interaction between an hydroelastic wave propagating along an elastic floating ice plate with built-in vertical rigid plate is studied. The fluid under the ice is inviscid and incompressible.
