Abstract
In the last decades, the public opinion has paid great attention to environmental pollution and global warming. Energy sector has a strong impact on environment. Thus, the use of renewable energies is becoming mandatory. The present paper deals with a study of ducted Savonius turbine performance as a function of geometric and operating parameters. Ducted turbines could be used as power take-off in multiple applications. In this paper, two main applications were studied. The first application is related to the possibility to install the turbine inside building with the purpose of architectonic integration of the system. The second one is related to wave energy harvesting. In both cases the same type of turbine was used to convert input energy (wind or wave energy) into electricity. Turbine performance were studied as a function of turbine overlap ratio, as well as air flux oscillating frequencies. On the basis of the obtained results, turbine performance increase in ducted configuration and a change in best overlap ratio was registered.
Highlights
In the last century an indiscriminate exploitation of energy sources has been made with the consequence of pollution and global worming dramatically increase
Pressure contribution allows an increase in power more than five times the power obtained with the same turbine bare
For that Overlap ratio (OR) an increase of about 40 % is registered in ducted configuration
Summary
In the last century an indiscriminate exploitation of energy sources has been made with the consequence of pollution and global worming dramatically increase. Strategies to slow down and even stop these problems should be considered in worldwide energy policies. Alternatives to reduce conventional energy sources utilization and its impacts are certainly the introduction of renewable energy in the energy scenario and decentralized power generation as a policy to reduce transportation waste. These strategies will contribute to a sustainable development of societies. Wind energy extraction in urban areas is a very interesting method for energy supply.
