We present a time-dependent, two-dimensional computational fluid dynamics (CFD) model coupled with the dynamics of the rotor for a height-normalized, small-scale high-solidity vertical axis wind turbine (VAWT) that consists of three straight blades, which are cambered to fit the circular path. The model employs the k-ε turbulence model to approximate unsteady Reynolds-averaged Navier-Stokes equations...
Control design plays an important role in wind energy conversion systems in achieving high efficiency and performance. In this study, hardware-in-the-loop (HIL) simulations are carried out to design a maximum power point tracking (MPPT) algorithm for small vertical axis wind turbines (VAWTs). Wind torque is calculated and applied to an electrical motor that drives the generator in the HIL simulator,...
In this paper, a new optimization approach based on Big Bang — Big Crunch optimization method to be employed in World Solar Challenge 2013 by Istanbul Technical University Solar Car Team is proposed. As much as the significance of renewable energy resources themselves, it is also important to optimally utilize them in an efficient way. World Solar Challenge is a biennially organized, 3021 km long...
