Placing a diffuser around a wind turbine can increase its power output, but not all mechanisms by which the diffuser alters the aerodynamics have been investigated thoroughly. Here, we concentrate on one such mechanism: the effect of the finite numbe

Flanged diffuser can improve hydrokinetic turbine efficiency. However, in the current literature it is still not clear if the flange allows the possibility of cavitation on its structure, and whether it can support high pressure variation. This work

In recent years, the study on wind turbines for electricity generation has achieved significant advances in the development of new formulations, analysis or even in efficiency. The growth in the use of wind technologies comes from two main facts: (i)

A growing interest has been devoted to turbines with diffusers, which induce a pressure drop downstream of the turbine to accelerate the fluid in the axial direction. This effect increases the axial aero- or hydrodynamic load on the turbine powertrai
