V. Jayashankar,S. Anand,T. Geetha,S. Santhakumar,V. Jagadeesh Kumar,M. Ravindran,T. Setoguchi,Manabu Takao,Kazutaka Toyota,Shuichi Nagata +9 more
TL;DR: In this paper, a new topology that uses twin unidirectional turbines (which feature a high efficiency spanning a broad range) is proposed, and it is shown that the power output from such a module considerably exceeds existing optimal configurations including those based on a fixed guide vane impulse turbine or a Well's turbine.
