A Study On The Self-Starting Characteristics Of H-Darrieus Turbine
Abstract
One of vertical axis turbines, H-Darrieus turbine has the advantage of being able to generate power at a low flow velocity compared to the horizontal axis one that is frequently used at present. However, the H-Darrieus turbine ironically has the disadvantage that it is difficult to self-start at low flow velocities. Therefore, in order to use the H-Darrieus turbine more efficiently, it is necessary to take the advantage of being able to generate electricity at a low flow velocity, and to do so, a study on the self-starting characteristics of the H-Darrieus turbine was required. Several key factors affecting self-starting in vertical-axis turbines can be specified as solidity, azimuth angle, Reynolds number, and angle of attack. In this study, the self-starting characteristics of the H-Darrieus turbine according to the change in solidity were investigated, and the self-starting characteristics of the multiple stage turbine were also analyzed. In order to study the effects of the solidity change and multiple stage on self-starting characteristics of the H-Darrieus turbine, the wind tunnel experiment zone and the turbine experimental apparatus were designed and manufactured, a control measurement system was built, and the linearity of the wind tunnel and the RPM sensor was investigated. And through the analysis of the results of previous studies, the appropriate self-starting criterion was selected and the experiment was conducted. As a result of the self-starting experiments, in the case of a large solidity, the incoming flow velocity that satisfies the self-starting criterion was low and the timing was fast, confirming that the self-starting characteristic was good. The result of multiple stage turbine was that the self-starting characteristics were poor because higher flow velocity and longer time were required as compared to the single stage turbine. In a future study, an power generation performance evaluation experiment will be conducted, and the self-starting and power generation performance evaluation will be used to design good H-Darrieus turbines.
