Effect of aspect ratio on hydrokinetic energy harnessing using cylinders in VIV
Journal of Ocean Engineering and Marine Energy - Tập 8 - Trang 217-232 - 2022
Smooth, rigid, circular cylinders on elastic support in flow perpendicular to their axis undergo vortex-induced vibrations (VIV) over a broad range of velocities. VIV converts hydrokinetic energy to mechanical in the oscillating cylinder. Tip-flow introduces three dimensional effects reducing the effective length of the cylinder which provides the transverse lift force to induce oscillations and c...... hiện toàn bộ

Parameter design and optimization for camber of vertical axis offshore wind turbine using CFD
Journal of Ocean Engineering and Marine Energy - Tập 6 - Trang 339-357 - 2020
This paper explores the camber as a variable to parameterize the airfoil of a 3-blade H-shaped vertical axis offshore wind turbine (VAOWT). The influence of airfoil camber (f) on the aerodynamics of H-type VAOWT is investigated. Selecting
$$v=4,8,12$$
m/s as the design conditions, and using NACA0015 airfoil (
$$f=0\%)$$
as the prototype to perform the parametric design of the airfoil. A total...... hiện toàn bộ
A CFD analysis of NREL’s 5MW wind turbine in full and model scales
Journal of Ocean Engineering and Marine Energy - Tập 6 - Trang 211-220 - 2020
In the present paper, a commercial CFD code based on RANS equations is used to assess the aerodynamic behavior of the rotor of NREL’s 5MW turbine. The main objective is to evaluate the changes that happen in the wind flow when the scale of the problem is reduced based on Froude-scale law, a procedure that is used for tests of floating wind turbines in wave basins, such as the ones performed as par...... hiện toàn bộ
Turning motion of multi-connection cross-flow vertical axis offshore wind turbines tension moored at a single point
Journal of Ocean Engineering and Marine Energy - Tập 9 - Trang 515-529 - 2023
This study proposes a multi-connection cross-flow vertical axis wind turbine, an innovative device to supply electric power in aquaculture farms. The device is a new type floating offshore wind turbine consisting of two independent wind turbine floats and a mooring float set in a straight line. A single-point mooring system with tension is utilized at the mooring float, which allows the wind turbi...... hiện toàn bộ
Submarine hydrodynamics for off-design conditions
Journal of Ocean Engineering and Marine Energy - Tập 8 - Trang 499-511 - 2022
Traditionally, submarine hydrodynamic design has focussed mainly on requirements regarding operational range, powering performance and manoeuvring ability for deeply submerged conditions. To improve the effectiveness of the boat, attention is also paid to operating near or at the surface and fortunately, computational tools and experimental methods are available to analyse the performance of subma...... hiện toàn bộ

A new concept for the safety of low-lying land areas from natural disasters
Journal of Ocean Engineering and Marine Energy - Tập 1 - Trang 19-29 - 2014
We introduce a new concept that utilizes floating foundations to create an urban community base in man-made inlets and basins—an idea that enables the attainment of a prosperous and sustainable urban and rural environment in the long term. This paper proposes the establishment of secure bases using a floating structure to safeguard from natural disasters, especially from flooding caused by heavy r...... hiện toàn bộ

Analysis of current influence on the wind wave parameters in the Black Sea based on SWAN simulations
Journal of Ocean Engineering and Marine Energy - Tập 9 - Trang 145-163 - 2022
This study is dedicated to the assessment of the current influence on the wind wave height in the Black Sea based on numerical modeling. The research was carried out based on the SWAN wave model driven by NCEP/CFSv2 wind reanalysis. Current data from the Remote Sensing Department's archive of the Marine Hydrophysical Institute of RAS were used. It is shown that the average wave height mainly decre...... hiện toàn bộ
