文摘
- •
A building-mounted diffuser is analyzed and shows that the flow can be accelerated inside a channel.
- •
A Savonius turbine is placed inside the diffuser shroud to extract energy from the flow.
- •
Computational Fluid Dynamics is used to calculate the coefficient of power.
- •
This paper presents a geometric optimization of the shroud diffuser and the location of the turbine.
- •
The coefficient of power of the turbine is improved from 0.135 to 0.34.
