Power generation utilizing the kinetic energy of river flow, tidal, and ocean currents have
encouraged the use of Darrieus turbines. However, the low power coefficient, poor self …

Abstract The influence of Computational Fluid Dynamics (CFD) modeling techniques on the
accuracy of fixed pitch vertical axis turbine power output predictions was investigated. Using …

The behavior of wind turbines wakes is of considerable interest, especially in the context of
wind farms where wake-turbine interactions are important. Here we investigate …

This paper numerically investigates the effect of the trailing edge profile on the performance
of the straight-blade vertical axis wind turbine (SB-VAWT). In a 2-D cross-section of the SB …

Navier-Stokes computational fluid dynamics simulations are expected to provide the basis
for a deeper understanding of the real behavior of vertical-axis wind turbines. The prediction …

The climate change due to emissions from the combustion of fossil fuel to meet the ever
increasing energy demands of the growing world population has roused the attention of …

The periodic changes of the angles of attack in time occurring in the Darrieus turbine blade
result in the significant increase of unsteady characteristics, commonly referred as dynamic …

Wind resource maps of annual-averaged wind speeds, typically used in the siting of wind
turbines and wind farms, can grossly underpredict the actual wind energy potential in areas …

The present study aims to analyze the structural behavior of the Darrieus Hydro-kinetic
turbine at different upstream velocity values and rotational rates. For that purpose, one-way …

CFD simulations of VAWT operation in unsteady wind conditions have been conducted.
Validation of the numerical model was carried out by comparison to experimental data of a …
