“…This approach involves the concept of phasic volume fractions, describing the space occupied by each phase (solid-liquid, gas-liquid, liquid-liquid) [29]. The laws of mass and momentum conservation are satisfied by each phase individually, the properties of each individual dispersed particle or droplet are averaged, and mass transfer between the phases is not assumed [2,14,26,27]. The presence of the dispersed phase has an important turbulent effect on the continuous phase that comes in the form of viscous drag [7].…”

A Review on the Estimation of Power Loss Due to Icing in Wind Turbines

The objective of this article is to review the methodologies used in the last 15 years to estimate the power loss in wind turbines due to their exposure to adverse meteorological conditions. Among the methods, the use of computational fluid dynamics (CFD) for the three-dimensional numerical simulation of wind turbines is highlighted, as well as the use of two-dimensional CFD simulation in conjunction with the blade element momentum theory (BEM). In addition, a brief review of other methodologies such as image analysis, deep learning, and forecasting models is also presented. This review constitutes a baseline for new investigations of the icing effects on wind turbines’ power outputs. Furthermore, it contributes to a continuous improvement in power-loss prediction and the better response of icing protection systems.

“…At present, the models used for the numerical analysis of wind turbine icing have been initially developed for aeronautical applications. For example, in the case of LEW-ICE, FENSAP-ICE, the Empirical tuned cylinder-based model by Makkonen, and TUR-BICE [2,14].…”

“…Ice problem solving techniques in wind turbines have improved in recent years (Pedersen and Yin, 2014). These techniques can be divided into two categories: the first method is to remove or prevent ice before it forms, the other method to remove ice after ice has formed (Parent and Ilinca, 2011).…”

The world’s energy demand is increasing. Wind energy plays an important role in meeting this demand. Investments in wind energy have been increasing in recent years. It can be said that the source of wind energy will be unlimited since there will be wind as long as there is sun. Most governments meet a large energy need by generating electricity from wind. At the end of 2019, the total amount of electricity generated from wind was 650 GW. Wind energy capacity is increasing with offshore wind pairs. Offshore wind turbines are a new field and research studies are ongoing. Wind turbines have the capacity to be installed anywhere in the world, and each government will have its own energy source. There is a problem of icing in wind power plants installed in cold climates. With this problem, efficiency in wind turbines decreases. Many methods have been found and developed in studies on icing problems. In this article, wind turbines were investigated, states’ perspectives on wind energy, developments and investments in wind energy, and the problem of icing were examined. Many articles in the literature have been reviewed and a solution to the icing problem of wind turbine blades has been sought.

Blade icing can affect wind turbines to generate electricity. In severe cases, 30% of power generation is lost in a year, and safety problems in the vicinity of wind power plants are also caused. Researchers have designed anti-icing and de-icing technologies to reduce these effects, and excellent ice-detecting devices are a prerequisite for using anti-icing and de-icing technologies. Ultrasonic attenuation technology can effectively and reliably detect the presence of ice without affecting the aerodynamic performance of the blade, providing a reliable guarantee for anti-icing and de-icing systems. Deicing and anti-icing systems are divided into active and passive, active heating blades are still the most effective anti-icing and de-icing methods, but their energy consumption is too high. Although there are many existing de-icing methods, there are not many practical uses. This article introduces them separately and lists their advantages and disadvantages. The use of ultrasonic anti-icing and de-icing is an economical and reliable means that has been proven to be used for anti-icing and de-icing of blades. However, under normal circumstances, a single anti-icing de-icing system cannot completely solve the problem of icing of the blades. This paper suggests using both ultrasonic and hydrophobic coatings to cope with more icing conditions.

Owing to release a lot of greenhouse gases, chemicals and toxins substances from the combustion of the fossil fuels such as coal and oil, 1 People began to look for renewable energy to provide energy consumption, such as wind energy, 2-4 hydrogen energy, 5-7 solar energy, 8-10 biogas and biomass energy. 11-15 With the wind power growing rapidly, generate electricity by using wind turbines is economical and environmentally friendly. 16 As can be seen in Figure 1, China's total installed capacity of wind turbines in 2016 is much higher than in other countries.China has the largest wind power market in the country, and the installed capacity of wind power is growing steadily year by year. The high density of air is conducive to the development of wind energy resources in cold regions. Figure 2 shows wind resource changes in different seasons. The wind speed from June to August is significantly lower than other months. There are also data showing that wind resources in cold regions are 10% higher than other regions. 17,18
