Abstract
The IceWind turbine, a new type of Vertical Axis Wind Turbine, was proposed by an Iceland based startup. It is a product that has been featured in few published scientific research studies. This paper investigates the IceWind turbine’s performance numerically. Three-dimensional numerical simulations are conducted for the full scale model using the SST K-ω model at a wind speed of 15.8 m/s. The following results are documented: static torque, velocity distributions and streamlines, and pressure distribution. Comparisons with previous data are established. Additionally, comparisons with the Savonius wind turbine in the same swept area are conducted to determine how efficient the new type of turbine is. The IceWind turbine shows a similar level of performance with slightly higher static torque values. Vortices behind the IceWind turbine are confirmed to be three-dimensional and are larger than those of Savonius turbine.
Highlights
Many factors have led to increased interest in renewable energy including the reduction in conventional energy sources, the fact that conventional energy sources cause climate change, and the availability and hygiene of renewable energy sources
Steady two-dimensional CFD simulations demonstrated that the new type had similar average static torque characteristics to present Savonius rotors

Summary
Many factors have led to increased interest in renewable energy including the reduction in conventional energy sources, the fact that conventional energy sources cause climate change, and the availability and hygiene of renewable energy sources. Numerically analyzed thethan aerodynamic performance of confirmed stationary that and ,Nasef the IceWind turbine produces less noise the Savonius turbine Simulations were two-dimensional demonstrated thetunnel new type similar average static torque achieved in a wayCFD thatsimulations allowed comparison withthat wind datahad documented in a related paper, characteristics to present. Dobrev and Massouh [7] aimed the significance to consider the flow through a Savonius type turbine using a three-dimensional model by means of k-ω and DES (Detached Eddy Simulation). Due to the continuous variation of the flow angle with respect to the blades and turbine principles of operation, strong unsteady effects including separation and vortex shedding were observed. Steady two-dimensional CFD simulations demonstrated that the new type had similar average static torque characteristics to present Savonius rotors.
