- … In particular, the spatial and temporal variation must be well understood. FloWave is a state-of-the-art test facility with the ability to produce multi-directional waves and currents. This … throughout the tank using an ADV. The goal is to provide a comprehensive characterisation of the flow in the tank, in a robust and repeatable manner. These flow parameters are then … measurements for context. The turbulence intensities are normally distributed in the range of 5–11% and integral lengthscales were log-normally distributed over a 0.18–0.41 m range across …
- … Tidal turbines encounter a range of unsteady flow conditions, some of which may induce severe load fluctuations. Rotor blades can experience stall delay, load hysteresis and dynamic stall. Yet, the range of flow conditions which cause these effects for a full-scale axial-flow turbine are unclear. In …
- … This paper presents a detailed parametric analysis on various input parameters of two different numerical models, namely Telemac3D and Delft3D, used for the simulation of tidal current flow at potential tidal energy sites in the Pentland Firth in Scotland. The motivation behind this work is to investigate the influence of the input parameters on the above 3D models, as the majority of past research has mainly …
- … government and devolved administrations. Attention has been drawn to this resource as a number of locations with high tidal current velocity have recently been leased by the Crown Estate for … velocity is too low for any power generation. However, it has been proposed that a portfolio of diverse sites located around the UK will deliver a firm aggregate output due to the relative phasing of the tidal signal around the coast. This paper analyses whether firm tidal power is feasible …
- … evaluate the maximum power that can be absorbed from a linear three-dimensional multi-degree-of-freedom system. A weighted global constraint is imposed on the system's excursions to ensure that the assumptions of linear theory remain valid. The numerical solution gives good agreement with known semi-analytical results for the case of a heaving hemisphere. A surging hemisphere is also studied, from which the relative merits of …
