    Comparative Study of Numerical and Experimental Aerodynamic Performance of NACA4412 Wind Turbine Airfoil Blade Section Under Atmospheric Icing Conditions
    Author(s): Ronald Okoth* and Ibrahim Kipngeno Rotich

    Wind energy is an emerging renewable energy but its reliability in cold regions is significantly affected by atmospheric icing. Ice accretion alters airfoil profiles by reducing energy production and increasing operational risks and maintenance costs. This study focused on the prediction of aerodynamic performance of iced airfoil blade sections through numerical approach using ANSYS Fluent and FENSAP ICE. The results obtained were verified with the experimental studies in a closed loop wind tunnel that was equipped to replicate the conditions for in-cloud icing phenomena. The ice accretion was numerically simulated with the aid of FENSAP ICE on NACA4412 airfoil at given conditions such as Liquid water content (LWC) of 0.8 g/m3 , 1.6 g/m3 , and 4.9 g/m3 , angle of attack of α=0 ° to 15 ° , and median volume diameter (MVD) of 50 μm, 51 μm and 54 μm.
