Abstract

Numerical simulations of rain droplet impacts on real rough surfaces of leading edges of wind turbine blades are presented. The effect of rough blade surface conditions during liquid impacts on the stress distribution in the protective coating is studied. Realistic rough surfaces of wind turbine blades, obtained from 3D reconstruction of real blades with photogrammetry, as well as artificially generated rough surfaces were introduced into finite element models of the droplet/blade coating interaction. Stress distributions in the protective coating with rough and flat surfaces were studied and compared. The results of the simulations suggest that roughness on the surface of the blade leads to increased stresses in the protective coating.

风力涡轮机叶片重建粗糙表面的侵蚀建模

数值模拟了雨滴对风力涡轮机叶片前缘真实粗糙表面的影响。研究了液体冲击过程中粗糙叶片表面条件对保护涂层应力分布的影响。将通过摄影测量对真实叶片进行三维重建获得的风机叶片真实粗糙表面以及人工生成的粗糙表面引入液滴/叶片-涂层相互作用的有限元模型中。研究并比较了粗糙和平坦表面保护涂层的应力分布。模拟结果表明，叶片表面的粗糙度会导致保护涂层中的应力增加。
