TL;DR: In this paper, a numerical study was carried out to investigate the effects of diffuser flange inclination angle (φ) and diffuser depth inside the exit of the diffuser (hi/Drotor) on the wind-lens turbine system performance.

TL;DR: In this article, the authors designed and simulated a water current stream energy conversion system as a stand-alone power station for the electric power generation in the River Nile in Egypt, which was selected as the case study for this kind of energy.

TL;DR: An assessment has been launched on two Archimedes Spiral Wind Turbine rotor designs, fixed and variable-angles, to get the best performance and demonstrates the higher performance of the variable-angle design over the fixed-angle one.

TL;DR: In this article, a parametric study was performed in which eight geometrical parameters for the stator were varied, and the results revealed that the rotor with optimum stator configuration achieved a value of 6 times greater than that of the bare rotor.

TL;DR: In this article, the performance of the Savonius turbine, fitted with auxiliary blades, is compared with a newly developed turbine where the gap ratio is studied, and the numerical simulation is carried out by solving unsteady Reynolds Averaged Navier-Stokes equations (URANS) using ANSYS fluent package.
