A system for generating renewable energy from fast flowing rivers has been designed in
a previous project. It uses a purely mechanical system to pump pressurised water to shore. Here we describe
the development of a 0.9m version of this system, designed for installation in a tidal estuary. The system is
fully instrumented to allow power take off an...
Numerical models are used for design and evaluation of tidal energy converters, helping to increase their appeal as significant contributors in the generation of low carbon energy. In this study, we quantify the improvement in predicted structural load variability achieved by incorporating more detailed consideration of foil shape and Reynolds effe...
Tidal energy converters have the potential to become significant contributors in the generation of low carbon energy. Operational cost, driven mostly by planned and unplanned maintenance, is one of the most significant barrier limiting their widespread adoption. Accurate numerical models can be used to predict structural loads and help improve thei...
This paper presents computations of a four tidal turbine array, with a row of three upstream devices and a downstream turbine. The studied configuration is based on the layout initially proposed in the framework of the NEPTHYD project. The simulations were carried out with a three-dimensional unsteady Lagrangian Vor-tex software. A synthetic eddy m...
Cost, driven mostly by planned and unplanned maintenance, is the most significant barrier limiting widespread adoption of TECs. Accurate numerical models can be used to predict the structural loads on TECs and help improve their reliability. BEMT offers an efficient method for predicting the performance of TECs. A robust but unoptimized BEMT code,...
During the design and development of ethylene propylene diene monomer (EPDM) exterior automotive seals, prototype components can only manufactured through production tooling platforms by either injection molding or extrusion. Consequently, tooling is expensive and has long lead times. This paper investigates whether additive layer manufacture is a...
