Abstract

This thesis has researched an innovative way of providing ‘zero carbon dioxide emitting electricity’ by the use of a patented novel wind or wind and solar building integrated energy system, the Aeolian Roof. The Aeolian Roof conceived and patented by Dr Derek Taylor, is specifically intended to act as a wind power concentrator, increasing the amount of wind resource available on the top of the building for wind energy exploitation. In order to achieve that, the Aeolian Roof uses a special fairing or wing-like 'planar concentrator' known as a SolAirfoilTM, which, in the particular arrangement examined in this thesis is attached and aligned to the upper region of the roof of a building.

The theoretical modelling of the Aeolian Roof has been undertaken with the aid of steady-state two dimensional Computational Fluid Dynamics (CFD) simulations. CFD results led to the construction of the first Aeolian Roof prototype on a dual pitch low-rise building located on an open country terrain. The experimental part of this work has shown that the Aeolian Roof concept works as a means of enhancing the power generated by a building-mounted wind turbine. For the Aeolian Roof configuration tested, it is possible to increase the wind power generated by a wind turbine in the Aeolian Roof by up to 60%. Means of achieving further enhancement have been identified as a result of this work and further testing is currently taking place.

The combination of hourly weather data and the experimental results have shown that for a site with an annual mean wind speed of 4.6 m/s on an exposed terrain the annual electricity produced with an Aeolian Roof should be capable of exceeding that generated over a year by the same wind turbine mounted on a mast - but able to yaw - by 12%. In terms of providing a value for the cost of the electricity generated with the Aeolian Roof, the analysis undertaken in this thesis has shown that for discount rates between 3.5% and 7.5% the cost of the electricity generated with the Mark 1 Aeolian Roof could be between 12 and 16 p/kWh respectively.
