... and the geometric angle of the blade leading edge. The rotor aerodynamic characteristics are examined entirely and locally in the following discussions. To examine the local characteristics, the rotor blade is divided into three segments, which are the hub-side, the midspan, and the tip-side regions and mean values...

.... The inherent unsteady and three-dimensional (3D) aerodynamics of vertical axis wind turbines (VAWT) have hitherto limited the research on wake evolution. In this paper, the wakes of both a troposkien and a H-type VAWT rotor are investigated by comparing experiments and calculations. Experiments were carried...

...) applications, since they can afford high pressure ratios per stage while keeping low rotational speeds. However, a careful design methodology is required to avoid large aerodynamic losses associated with the formation of shock waves and shock/boundary layer interactions. Now, in ORC turbines, the fluid evolves...
