2D CFD Simulation Study on the Performance of Various NACA Airfoils

The wind is an energy source that has the properties of a clean, free, and readily available source. However, efficiency existing rotors used to harness power still not satisfactory. Thus, in this current study, development aerodynamic performance investigation ten NACA airfoils comprising five symmetrical non-symmetrical have been analyzed through computational fluids dynamic (CFD) simulation approach. main motive study was investigate be on vertical axis turbine (VAWT), which will assist further understanding physics interaction between airflow blades. performed using two-dimensional models based unsteady state K-omega Shear Stress Transport (SST) turbulence model. This covers parametric variations tip-speed ratios constant velocity. performances are evaluated terms torque, torque coefficient, also coefficient. NACA0018 found best among other with coefficient 0.3. NACA0010 displayed lowest but had more extensive operating range compared airfoils. for airfoils, NACA2421 scored highest followed by NACA4412. It most can operate at higher
