During the last decade, there was an increased interest in wind turbine icing. Most of the icing studies are related to horizontal axis wind turbine icing (HAWT). Vertical axis wind turbine (VAWT) icing is seldomly reported in the literature. Compared to the HAWT blade VAWT blade operates under various angles of attack. Therefore, ice accretion shapes on static VAWT blade must be considered under different angles of attack. In the present study, a novel approach to predict ice accretion shapes on VAWT is described. Ice accretion shapes are obtained at a range of angles of attack between −25° and 25° using FENSAP-ICE which is the state-of-art icing simulation tool. Moving reference frame (MRF) was used to consider rotating effect on droplet field. The present method helped to draw the following conclusions. Firstly, the whole leading edge is covered by ice. Secondly, in rime ice conditions smooth ice shape is obtained, which does not significantly affect aerodynamic performance. Whereas in glaze ice conditions bumpy ice shapes causing massive flow separation and lift force degradation. Finally, iced VAWT loses up to 60% of power performance due to rime ice conditions. In glaze ice conditions VAWT is unable to produce power.

在过去的十年中，人们对风力涡轮机的积冰越来越感兴趣。大多数的结冰研究都与水平轴风力发电机的结冰（HAWT）有关。文献中很少报道垂直轴风力涡轮机（VAWT）的结冰情况。与HAWT刀片相比，VAWT刀片可在各种迎角下运行。因此，必须在不同的迎角下考虑静态VAWT叶片上的积冰形状。在本研究中，描述了一种预测VAWT上结冰形状的新颖方法。使用最新的结冰模拟工具FENSAP-ICE，可在-25°和25°的迎角范围内获得积冰形状。使用移动参考系（MRF）考虑旋转对液滴场的影响。本方法有助于得出以下结论。首先，整个前沿被冰覆盖。其次，在霜冰条件下，可获得光滑的冰形状，这不会显着影响空气动力性能。而在釉冰条件下，颠簸的冰形状会导致大量的流分离和升力下降。最后，由于霜冰条件，结冰的VAWT会损失高达60％的功率性能。在釉冰条件下，VAWT无法发电。
