Allowable Pitch Angle of Aerodynamic Imbalance Due to Individual Pitch Movement for Ultimate Loads on Offshore Wind Turbine Using Artificial Neural Network
Autor: Bae-Sung Kim, Dae-Yi Jung, Yun-Jung Jang, Ki-Weon Kang
Publikováno v: Applied Sciences, Vol 12, Iss 10, p 5177 (2022)
This study aims to calculate the ultimate loads through integrated load analysis under aerodynamic imbalance by individual pitch movement of offshore wind turbines, and based on this, to identify the allowable region of the individual pitch angle of

Identification of Debonding Damage at Spar Cap-Shear Web Joints by Artificial Neural Network Using Natural Frequency Relevant Key Features of Composite Wind Turbine Blades
Autor: Yun-Jung Jang, Hyeong-Jin Kim, Hak-Geun Kim, Ki-Weon Kang
Publikováno v: Applied Sciences, Vol 11, Iss 12, p 5327 (2021)
As the size and weight of blades increase with the recent trend toward larger wind turbines, it is important to ensure the structural integrity of the blades. For this reason, the blade consists of an upper and lower skin that receives the load direc

Quantitative Analysis and Band Gap Determination for CIGS Absorber Layers Using Surface Techniques
Autor: Yun Jung Jang, Jihye Lee, Kang-Bong Lee, Donghwan Kim, Yeonhee Lee
Publikováno v: Journal of Analytical Methods in Chemistry, Vol 2018 (2018)
Recently, Cu(InXGa(1−X))Se2 (CIGS) absorber layers have been extensively studied by many research groups for thin-film solar cell technology. CIGS material is particularly promising due to its exceptionally high absorption coefficient and large ban
