Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

An analytical model based on the double multiple streamtube method is proposed for calculating the rotor performance and aerodynamic blade forces for vertical axis wind turbines (VAWTs) with variable pitch straight blades. An interception method is utilized to determine induction factors which can be used to calculate local blade forces. The model makes allowance for flow expansion, flow curvature, tip loss and dynamic stall. Aerodynamic prediction output from this model is compared with experimental data available in the public domain for validation purposes.
