Elucidation of aerodynamic characteristics due to ice accretion on multi-mw wind turbine blade
Wind turbines installed in regions with high altitudes and low temperatures on winter season, ice can accumulate on the blade surfaces during operating condition. A small amount of ice accretion on the blade surface can result in several crucial issues, such as AEP (annual energy production) reduction due to degrade aerodynamic performance, and safety concerns related to ice falling down. Predicting and elucidating icing accretion phenomena under various weather conditions are significantly essential in the aspect of operating and maintenance. The primary objective of this study was to assess the impact of ice accretion on the aerodynamic characteristics of wind turbine blades CFD (computational fluid dynamics) analysis, including ice thickness and shape, under varying weather conditions. Therefore, this study focused on identifying the aerodynamic characteristics affected by ice accretion, including ice thickness and shape under various weather conditions through Fensap. Through this methodology, the presence of ice accumulation on the blade surfaces was investigated, and its adverse impact on aerodynamic performance has been assessed.
期刊介绍：
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
