Comparative study of indirect tensile test and uniaxial compression test on asphalt mixtures: Dynamic modulus and stress-strain state
(Peer reviewed; Journal article, 2022)Dynamic modulus is an essential parameter for the performance characterisation of asphalt materials for performance prediction and pavement design. The Indirect Tensile (IDT) test and the Uniaxial Compression (UC) test are ... -
Comparative study on loosening of anti-loosening bolt and standard bolt system
(Peer reviewed; Journal article, 2022)In general, bolted connections are exposed to vibrations or repeated over-loads that could lead to self-loosening due to loss of preload. Pre-tensioned bolts in ring flanges are critical parts in Offshore Floating Wind ... -
Comparing different CFD wind turbine modelling approaches with wind tunnel measurements
(Peer reviewed; Journal article, 2014)The performance of a model wind turbine is simulated with three different CFD methods: actuator disk, actuator line and a fully resolved rotor. The simulations are compared with each other and with measurements from a wind ... -
Comparison of unidirectional and bidirectional airfoils in a tidal stream turbine
(Peer reviewed; Journal article, 2022)Tidal stream turbines offer an attractive method for stable renewable energy generation. Due to the periodicity of the tidal stream, a tidal stream turbine can be designed to operate in a bidirectional manner, thereby ... -
A comparison study of power performance and extreme load effects of large 10-MW offshore wind turbines
(Peer reviewed; Journal article, 2023)The utilisation of offshore wind turbines has rapidly increased in the last decade, which has resulted in a steady increase in wind turbine sizes. The global average offshore wind turbine size has increased from 1.5 MW to ... -
A compensation scheme applied on wind turbine blade pitch control for the reduction of non-torque main shaft loads
(Peer reviewed; Journal article, 2021)It has been well established that non-torque main shaft loads influence the internal drive train loads. This paper proposes a scheme that compensates for non-torque loads in the blade pitch controller. The compensation ... -
Composite Overwrapped Pressure Vessel Design Optimization Using Numerical Method
(Journal article; Peer reviewed, 2022-08-05)Composite Overwrapped Pressure Vessels (COPVs) are widely used in fields including aeronautics and by companies such as SpaceX to hold high pressure fluids. They are favored for these applications because they are far ... -
Computational investigation of the aerodynamic performance of reversible airfoils for a bidirectional tidal turbine
(Peer reviewed; Journal article, 2021)A reversible airfoil is an airfoil that has equal performance when the flow is reversed. Such airfoils are relevant for many different applications, including use in ventilation fans, helicopter rotors, wind turbines and ... -
Concerns to Be Considered During Recycling Operations
(Peer reviewed; Journal article, 2019)Recycling should in principle be the goal in all aspects of society. There are, however, limitations, as any recycling task may lead to pollution in the ground, water or air. In the most extreme case, recycling may lead ... -
Contact stresses associated with the wedge-lock mechanism in a prototype subsea pipeline recovery tool
(Peer reviewed; Journal article, 2019)This paper examines the contact stresses associated with the wedge-lock mechanism in a prototype subsea pipeline recovery tool (PRT) through numerical methods and experimental testing. The prototype PRT studied combines ... -
Contact temperature analysis of the classical Geneva mechanism through numerical methods
(Peer reviewed; Journal article, 2022)In this study, the flash temperature of the classical Geneva mechanism has been studied using the numer- ical method. An excessive sliding motion between the wheel and pin leads to the generation of heat at the contact ... -
Context analysis of Offshore Fish Farming
(Peer reviewed; Journal article, 2019-11)The in-land and nearshore fish farming is facing capacity limitation and onshore push-out regulations. Huge technological innovations are rapidly evolving toward developing competitive Offshore fish farming. These technological ... -
The Contribution of Building-Integrated Photovoltaics (BIPV) to the Concept of Nearly Zero-Energy Cities in Europe: Potential and Challenges Ahead
(Peer reviewed; Journal article, 2021-09)The main purpose of this paper is to investigate the contributions of building-integrated photovoltaic (BIPV) systems to the notion of nearly zero-energy cities in the capitals of the European Union member states (EU), ... -
Convolutional Neural Networks and Feature Fusion for Flow Pattern Identification of the Subsea Jumper
(Peer reviewed; Journal article, 2023)The gas–liquid two-phase flow patterns of subsea jumpers are identified in this work using a multi-sensor information fusion technique, simultaneously collecting vibration signals and electrical capacitance tomography of ... -
