Wind tunnel tests were conducted to systematically assess the aerodynamic performance of
both H-rotor and helical vertical axis wind turbines (VAWTs) in smooth and turbulent flows …

Although freestream turbulence is believed to improve the efficiency of vertical axis wind
turbines (VAWTs), few studies have systematically assessed VAWT performance in turbulent …

The present study proposes a new concept of Straight-bladed Vertical Axis Wind Turbines
(SB-VAWTs) with convex-shaped wind concentrator. The wind concentrator is installed up …

Wind turbine blades in wind farms often exhibit damage in extreme turbulence generated by
typhoons, tornadoes, and canyon winds. To address this issue, a continuous aerodynamic …

There are different methods for setting the inlet boundary condition (IBC) in large eddy
simulation (LES). However, different methods applied in the same simulation result in …

We present a study on the influence of the turbulence generated by a cylinder on the
performance of a free horizontal-axis turbine. The analysis focuses on the power coefficient …

The effect of variations in the integral length scale of incoming free-stream turbulence on a
NACA0012 wing is investigated with the use of force, moment and particle image …

The aerodynamic dam** reflects the aero-structure interaction and is intrinsically involved
in a fully coupled turbine. However, it is still of great importance to theoretically quantify the …

Physical imaging is a foundational characterization method in areas from condensed matter
physics and chemistry to astronomy and spans length scales from atomic to universe …

This work presents a new methodology to evaluate the influence of wind speed data
corrections in the fit of the Weibull distribution. Corrections are made for data measured by …
