TLDR
In this article, the performance of the biplane turbine was investigated in unidirectional steady air flow by varying the model configurations using solidity, gap to chord ratio and stagger angle.Abstract:
The paper describes experimental investigation of the biplane Wells turbine for a wave power plant. Performance of the biplane turbine was investigated in unidirectional steady air flow by varying the model configurations using solidity, gap to chord ratio and stagger angle. It was concluded that the performance of the biplane turbine is considerably influenced by inviscid and viscous flow effects. Adjacent upstream and downstream pressure distributions will either suppress or enhance one-another depending on stagger given sufficiently small G/c ratio. The viscous effect from the upstream wake seems to defer stall by advancing boundary layer transition.read more
