Effect of T-groove Parameters on Steady-State Characteristics of Cylindrical Gas Seal
(Peer reviewed; Journal article, 2020)Gas film seal technology is becoming increasingly important as an advanced new rotary shaft seal technology in aviation engines and industrial gas turbines. In this paper the impacts of several parameters of T-groove ... -
Effect of the angle of attack on flow around an elliptic cylinder near a moving wall
(Journal article; Peer reviewed, 2022)The present work investigates the combined effect of the angle of attack (AOA) (the angle between the semi-major axis of the cylinder and the vertical axis), and the gap ratio G/D (where G represents the distance between ... -
Effect of the number of blades on the dynamics of floating straight-bladed vertical axis wind turbines
(Journal article; Peer reviewed, 2017)Floating vertical axis wind turbines (VAWTs) are promising solutions for exploiting the wind energy resource in deep waters due to their potential cost-of-energy reduction. The number of blades is one of the main concerns ... -
Effect of Time Delays and Sampling in Force Actuated Real-Time Hybrid Testing; A Case Study
(Chapter, 2017)This paper presents a study where real-time hybrid testing is applied on a double mass-damper-spring system. Simulations show how delays and sampling terms affect the system both when it is subjected to excitations forces ... -
Effect of wave inhomogeneity on fatigue damage of mooring lines of a side-anchored floating bridge
(Peer reviewed; Journal article, 2020)Mooring systems are important structural components of very long floating bridges. They effectively limit the transverse motions of the bridge under environmental loads. They also add viscous hydrodynamic damping to the ... -
Effect of wave nonlinearity on fatigue damage and extreme responses of a semi-submersible floating wind turbine
(Journal article; Peer reviewed, 2019)Floating wind turbine has been the highlight in offshore wind industry lately. There has been great effort on developing highly sophisticated numerical model to better understand its hydrodynamic behaviour. A engineering-practical ... -
Effect of Wave Skewness and Sediment Particle Size on Sediment Transport Due to Combined Wave-Current Seabed Boundary Layer Streaming
(Peer reviewed; Journal article, 2022)The effect of wave skewness and sediment particle size on near-bed sediment dynamics and transport owing to wave-induced streaming is examined in this study. Here, wave-dominated flow over a flat rough bed is studied, with ... -
Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge
(Peer reviewed; Journal article, 2022)Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ... -
Effect of Wave-Current Interaction on Structural Responses of a Very Long and Side-Anchored Floating Bridge
(Chapter, 2020)This paper is concerned with a computational study on the hydroelastic response of a long, straight and side-anchored fjord-crossing floating bridge accounting for the wave-current interaction. The effect of this interaction ... -
Effect of waves on cavitation and pressure pulses
(Journal article, 2016)In view of environmental concerns, there is increasing demand to optimize the ships for the actual operating condition rather than for calm water. Now, in order to apply this for propeller design, a first step would be to ... -
Effect of waves on cavitation and pressure pulses of a tanker with twin podded propulsion
(Journal article, 2017)There is increasing interest in optimizing ships for the actual operating condition rather than just for calm water. In order to optimize the propeller designs for operations in waves, it is essential to study how the ... -
Effect of wind speed distribution and site assessment on pitch bearing loads and life
(Peer reviewed; Journal article, 2023)In this paper, the wind speed distribution at thirteen onshore and offshore wind sites has been studied. Different probability distributions are used to estimate the wind speed distribution. Several goodness-of-fit indicators ... -
Effective utilization of service vessels in fish farming: Fleet design considering the characteristics of the locations
(Peer reviewed; Journal article, 2022)Effective utilization of service vessels in sea-based fish farming requires that the vessels are suited to the operating environments at the fish farms. This paper presents a methodology for assessing service vessel fleet ... -
