“…Sean et al investigated the effects of glaze ice and freezing ice conditions on wind turbine aerodynamics through numerical simulations. It was found that more ice is formed at lower temperatures in freezing ice conditions, and the wind turbine performance was reduced by a maximum of 40% [27]. Mustafa et al investigated the static performance of a wind turbine at different uniform wind speeds between cut-in and cut-out wind speeds by simulating and analyzing a 5 MW wind turbine blade with light icing.…”

The icing of wind turbine blades can cause changes in airfoil shape, which in turn significantly reduces the aerodynamic performance and affects the power generation efficiency of a wind turbine. In this paper, the iced airfoil shape of wind turbine blades with different positions, masses, and angles of attack icing was measured and modeled using 3D scanning technology, and changes in airfoil shape parameters under different icing conditions were obtained. The numerical simulations of icing blades were carried out to investigate the effect of blade icing on aerodynamic characteristics. The results show that ice accumulation thickness tends to increase nonlinearly along the spanwise direction and chord length for both windward and leeward icing. The airfoil angle of attack affects the trend of ice accumulation changes. As shown by the numerical simulation of the aerodynamic characteristic, blade icing changes the airfoil shape, which changes the pressure difference between the leading edge and trailing edge, affects the size and number of the wake vortex structures, and further changes the aerodynamic characteristics of the blade.

Ice accretion on aircrafts due to atmospheric conditions is still a relevant research topic, especially in the case of Unmanned Aerial Vehicles (UAVs), due to their smaller size and the relative underdevelopment of ice protection systems (anti-icing and de-icing) for these aircraft. For the research and development of these systems, it is necessary to assess their performance in icing wind tunnels (IWTs), which are generally high-cost facilities. This article describes the design and building process of a new IWT for testing fixed-wing UAVs, aimed at cost reduction and restricted to an existing cold climate chamber of limited size. The designed IWT is an open-circuit type with two corners, a test section size of 0.40 m × 0.27 m and speed up to 70 m/s. The design process employs widely used and proven semi-empirical formulas, supported by detailed calculations using Computational Fluid Dynamics (CFD) tools, to achieve a test section core of useful quality and avoid flow separation. Theoretical limits with respect to a usable droplet size and Liquid Water Content (LWC) are calculated, and the test section core is estimated. The design process followed proves to be a very good approach to the design and aerodynamic optimisation of a low-cost IWT.
