(Journal article, 2015)The mooring loads on an aquaculture net cage in current and waves are investigated by dedicated model tests and numerical simulations. The main purpose is to investigate which physical effects are dominant for mooring ... -
Experimental and numerical study of hydrodynamic responses of a combined wind and wave energy converter concept in survival modes
(Journal article; Peer reviewed, 2015)The Spar Torus Combination (STC) concept consists of a spar floating wind turbine and a torus-shaped heaving-body wave energy converter (WEC). Numerical simulations have shown a positive synergy between the WEC and the ... -
Experimental and numerical study of mooring chain residual stresses and implications for fatigue life
(Peer reviewed; Journal article, 2020)Residual stresses in large mooring chains were measured for the first time in this study. Two measurement techniques were employed (neutron diffraction and hole drilling). Elastic-plastic finite element simulation of the ... -
Experimental and numerical study of notched SHS made of different S355 steels
(Peer reviewed; Journal article, 2021)This study compares the mechanical behaviour of square hollow sections (SHS) made of three different types of S355: cold-formed, hot-rolled and offshore steel. A material model and failure criterion for each steel type ... -
Experimental and numerical study of the response of the offshore combined wind/wave energy concept SFC in extreme environmental conditions
(Journal article; Peer reviewed, 2016)This paper deals with an experimental study of the survivability of the offshore combined concept Semisubmersible wind energy and Flap-type wave energy Converter (SFC) and with comparisons of the experimental data with ... -
Experimental and Numerical Study of Waves Breaking Over a Submerged Three-Dimensional Bar
(Peer reviewed; Journal article, 2022)Depth-induced breaking is the major wave transformation process in coastal waters that significantly influences the wave energy that eventually reaches the coastline. Most studies of depth-induced wave breaking focus on ... -
Experimental and numerical study on hydrogen-induced failure of X65 pipeline steel
(Peer reviewed; Journal article, 2024)Hydrogen-induced fracture of X65 pipeline steel under in-situ electrochemical charging is investigated by using in situ slow strain-rate tensile (SSRT) test, hydrogen diffusion test, fractography analysis, and finite element ... -
Experimental and Numerical Study on Tapping of Two Liquids through a Single Tap-Hole
(Journal article; Peer reviewed, 2023)The production of industrial metals in pyrometallurgical smelting furnaces is central to modern industry. Tapping of metal and slag from smelting furnaces is a complex and difficult process. Any variations from tap to tap ... -
Experimental and numerical study on the behaviour of PVC and HDPE in biaxial tension
(Journal article; Peer reviewed, 2012)This paper presents and discusses a set of biaxial tests on two different polymer materials; PVC and HDPE. The biaxial tests are used to evaluate a hyperelastic–viscoplastic constitutive model involving the pressure-dependent ... -
Experimental and numerical study on the R744 ejector with a suction nozzle bypass
(Peer reviewed; Journal article, 2021)State-of-the-art R744 cooling cycles include highly efficient ejectors as a crucial element for competitive energy consumption in warm climates. However, an improvement is still possible, as shown in this study. This study ... -
Experimental and numerical validation of an analytical hydro-plastic model for the prediction of structural damage in extreme water slamming
(Chapter, 2021)Extreme water slamming poses great threats on the safety of ships and offshore structures at sea, which may in the extreme conditions cause large structural damage, progressive collapse of structures and even fatalities. ... -
Experimental and numerically obtained low-frequency radiation characteristics of the OC5-DeepCwind semisubmersible
(Peer reviewed; Journal article, 2021)Added mass and damping play a significant role in accurate prediction of floating wind turbine (FWT) motions, especially near the resonance frequencies. This paper investigates the still-water hydrodynamic characteristics ... -
Experimental and simulated evaluations of airborne contaminant exposure in a room with a modified localized laminar airflow system
