Imai studies on ice accretion
WitrynaIn this experimental and theoretical study the ice accretion phenomena on a heated cylinder in Braunschweig Icing Wind Tunnel are investigated. The ice crystal size, … WitrynaFor 2D simulations, nine sections along a 300 kW wind turbine blade are selected, whereas for 3D study, a full-scale blade is used. The obtained results show a significant difference in the ice accretion for both approaches. Higher ice growth is observed in 2D approach when compared with the full-scale 3D simulations.
