Experimental Study on Conversion Characteristics of Dual-Mode OWC Models Appropriate for Voyaging
China Ocean Engineering - Tập 37 - Trang 247-257 - 2023
Freely movable wave energy converters (WECs) will greatly improve their adaptability to the marine environment. In this paper, a dual-mode oscillating water column (OWC) WEC with potential sailing capability is proposed. By opening and closing a gate on the side facing the waves, the WEC converts wave energy in the vertical duct (called VD mode) with low sailing resistance or in the backward bend ......
Effect of under connected plates on the hydrodynamic efficiency of the floating breakwater
China Ocean Engineering - Tập 28 - Trang 349-362 - 2014
In this paper, the hydrodynamic efficiency of a floating breakwater system is experimentally studied by use of physical models. Regular waves with wide ranges of wave heights and periods are tested. The efficiency of the breakwater is presented as a function of the wave transmission, reflection, and energy dissipation coefficients. Different parameters affecting the breakwater efficiency are inves......
Penetration Depth of Torpedo Anchor in Two-Layered Cohesive Soil Bed by Free Fall
China Ocean Engineering - Tập 32 - Trang 706-717 - 2018
The penetration depth of torpedo anchor in two-layered soil bed was experimentally investigated. A total of 177 experimental data were obtained in laboratory by varying the undrained shear strength of the two-layered soil and the thickness of the top soil layer. The geometric parameters of the anchor and the soil properties (the liquid limit, plastic limit, specific gravity, undrained shear streng......

Analysis for the deployment of single-point mooring buoy system based on multi-body dynamics method
China Ocean Engineering - Tập 26 - Trang 495-506 - 2012
Deployment of buoy systems is one of the most important procedures for the operation of buoy system. In the present study, a single-point mooring buoy system which contains surface buoy, cable segments with components, anchor and so on is modeled by applying multi-body dynamics method. The motion equations are developed in discrete node description and fully Cartesian coordinates. Then numerical m......
Experimental study on mechanism and shape characteristics of suspended flexible dam
China Ocean Engineering - Tập 28 - Trang 869-878 - 2014
Hydraulic structures such as groin, longitudinal dike and seawall are common in water conservancy and water transportation engineering projects at home and abroad, which have long been dominated by solid mass structural form. With brush and stone as building materials, this kind of structure has an obvious engineering effect. However, it not only requires huge capital investments, but also has neg......

Experimental modelling of transverse oscillations in aquaculture netting parallel to the flow — Sounds baffling
China Ocean Engineering - Tập 29 - Trang 391-400 - 2015
Numerous studies have been undertaken to improve the viability, durability and suitability of materials and methods used for aquaculture enclosures. While many of the previous studies considered macro-deformation of nets, there is a paucity of information on netting micro-deformation. When aquaculture pens are towed, industry operators have observed the motion described as “baffling” — the transve......
Regional-Scale Study on Sediment Processes of Khuran Strait at Persian Gulf with Implications for Engineering Design
China Ocean Engineering - Tập 33 - Trang 356-364 - 2019
In this article, the sediment transport processes in the Khuran Strait between the mainland Iran and Qeshm Island at North Central Persian Gulf are studied in regional scale in a comprehensive manner. The objectives of this study include defining the type and origin of the sediment, the influencing factors, and the dominant mode of sediment transport. Four possible scenarios of sediment processes ......
