“…Salik et al [119] found that sharp-shaped sand particles cause a greater erosive shock than rounded particles, with an order of magnitude difference. Finally, in one of the studies in [110], the density of sand particle has been taken as 2200 kg/m 3 .…”

“…One of the most prevalent factors is the presence of rain and the subsequent rain erosion of the leading edge of wind turbine blades (Figure 1). Damage caused by impacts from other projectiles, including hail [1][2][3], sand [4][5][6][7], insects [8,9] and birds, also contributes to the degradation. However, they are less understood and particularly site specific, with early research on hail erosion displaying little erosion damage [3], insects preferring warm humid air for flight [9], sand being mainly present in dry, arid areas or certain coastal sites [7] and turbine siting and development aiming to minimise bat or bird strikes.…”

Leading edge erosion is becoming increasingly important as wind turbine size and rainfall are predicted to increase. Understanding environmental conditions is key for laboratory testing, maintenance schedules and lifetime estimations to be improved, which in turn could reduce costs. This paper uses weather data in conjunction with a rain texture model and wind turbine RPM curve to predict and characterise rain erosion conditions across Ireland during rainfall events in terms of droplet size, temperature, humidity and chemical composition, as well as the relative erosivity, in terms of number of annual impacts and kinetic energy, as well as seasonal variations in these properties. Using a linear regression, the total annual kinetic energy, mean temperature and the mean humidity during impact are mapped geospatially. The results indicate that the west coast of Ireland and elevated regions are more erosive with higher kinetic energy. During rain events, northern regions tend to have lower temperatures and lower humidities and mountainous regions have lower temperatures and higher humidities. Irish rain has high levels of sea salt, and in recent years, only a slightly acidic pH. Most erosion likely occurs during winters with frequent rain infused with salt due to increased winds. After this analysis, it is concluded that Ireland’s largest wind park (Galway) is placed in a moderate-highly erosive environment and that RET protocols should be revisited.
