This paper describes a brief overview of main issues related to atmospheric ice accretion on wind turbines installed in cold climate region. Icing has significant effects on wind turbine performance particularly from aerodynamic and structural integrity perspective, as ice accumulates mainly on the leading edge of the blades that change its aerodynamic profile shape and effects its structural dynamics due to added mass effects of ice. This research aims to provide an overview and develop further understanding of the effects of atmospheric ice accretion on wind turbine blades. One of the operational challenges of the wind turbine blade operation in icing condition is also to overcome the process of ice shedding, which may happen due to vibrations or bending of the blades. Ice shedding is dangerous phenomenon, hazardous for equipment and personnel in the immediate area.

Abstract. One of the emerging problems in modern computational fluid dynamics is the simulation of flow over rough surfaces, wind turbine blades with ice on its surface for instance. An alternative method to numerically simulate rough surfaces instead of using a grid with y+

This article aims to predict ice loads on a wind turbine blade section at 80% of blade span, using FENSAP ICE. Using low and high liquid water content conditions of stratiform and cumuliform clouds, different icing events are simulated. Ice accretion predictions with single-shot and multi-shot approaches are presented. Blade surface roughness is also investigated, as well as the relationships between ice mass, liquid water content, median volume diameter, and temperature.

A review on icing physics, ice detection, anti-icing and de-icing techniques for wind turbines in cold climate has been performed. Typical physical properties of atmospheric icing and the corresponding meteorological parameters are presented. For computational modeling of ice accretion on turbine blades, the LEWINT code was adopted to simulate ice accretion on an aerofoil for a 2 MW wind turbine. Ice sensors and the basic requirements for ice detection on large blades are described. Besides, this paper presents the main passive and active ice mitigation techniques and their advantages and disadvantages. Scope of future work is suggested as wind turbine blades scale up.
