Abstract IceWind turbine, a new type of Savonius Wind Turbine, is proposed by an Iceland based startup. It is a product without any published scientific research. As an innovative type, it desires explorations. This paper investigates experimentally its performance. It also makes a parametric study. An optimum design is discovered and a comparison between the proposed two blades IceWind and Savonius wind turbine of the same swept area is completed. Experiments are conducted taking into account these parameters; number of blades, existence of end plates, number of stages, aspect ratio and blade arc angle. The experiments are performed in a wind tunnel at five wind speeds (8.4, 9.4, 11.5, 13.7 and 15.8 m/s). Turbines are built using Aluminum sheets. Static torque in Nm and rotational speed in rpm are measured using digital torque meter and digital tachometer, respectively. From steps, it can be concluded that a single stage three blades IceWind turbine with end plates, aspect ratio of 0.38 and blade arc angle of 112 o gives greater performance. IceWind turbine shows similar performance with slightly higher values of static torque and rotational speed when compared with Savonius wind turbine. Dynamic similarity, uncertainty analysis and comparison with previous data are informed. Keywords: IceWind Turbine, Savonius Turbines, Experimental, Wind Tunnel, Rotational speed, Static Torque and Coefficient of Static Torque. 1. INTRODUCTION IceWind is a new type of Savonius Vertical Axis Wind Turbine. The prefix Ice, in its name “IceWind”, is related to “Iceland” its home town. Through navigating its website [1], the language of Iceland “Islenska” appeared beside English language in the upper right corner. Currently, there are two products; IceWind CW turbine, Fig.1, and IceWind RW turbine, Fig.2, without a single published paper. Due to lack of data for IceWind turbine to compare its performance, Savonius wind turbine’s previous studies will help.  Mohamed et al. [2], Menet [3], Saha et al. [4], Mahmoud et al. [5], Bhayo and Al-Kayiem [6] and Al-Kayiem et al. [7] studied the effect of number of blades. Comparisons between two and three blades rotor were made. They concluded that a two blades rotor gives higher efficiency and higher power coefficient. Fig.1. CW IceWind turbine. Fig.2. RW IceWind turbine.  Saha et al. [4], Mahmoud et al. [5], Nasef et al. [8] and Blackwell et al [9] studied the effect of single, double and triple stages rotors. Double stages rotors got the optimum efficiency.  Aspect Ratio (AR) is defined as the ratio between rotor height and rotor diameter. Bhayo and Al-Kayiem [6] revealed that aspect ratio increased from 0.77 to 2.0. Al- Kayiem et al. [7], Alexander and Holownia [10], Sivasegaram [11] and Kamoji et al. [12] realized that there is an increase in power coefficient with the rise in aspect ratio. Some of them concluded that the optimum value of AR is 0.77.  Blade arc angle (ψ) describes the angular curvature of the cross-section of blade. Kamoji et al. [12] declared that a rotor with a blade arc angle of 124° is having power coefficient higher than rotors with other blade arc angles. However, Mahamarakkalage [13] and Kumar and Saini [14] concluded that the optimum value of blade arc angle is equal to 135° and 150°, respectively. * Corresponding Author: AASTMT, Abu kir, Alexandria, P.O.Box1029-Miami, Egypt.
