Comparative Study of Different Wind Turbine Blade Profile for Optimization on the Basis of Maximum Gliding Ratio and Lift Force: An Investigation by MATLAB Simulation

In present paper, MATLAB analysis for comparative study of different wind turbine blade profile for optimization of the two-dimensional subsonic flow over different airfoils at various angles of attack is presented. Lift coefficient (Cl), drag coefficient (Cd), gliding ratio (GR), and lift force (FL) are determined. The geometry of the airfoil is created using MATLAB R2018a analysis tool. Figures 1, 2, 3, 4, 5 6, 7, 8, 9 and 10 represents the individual geometry of different NACA aerofoil, Figs. 11, 12, 13 and 14 is comparative study of different NACA aerofoil for angle of attack vs lift force, gliding ratios, lift coefficient, and drag coefficient. The optimization process goes further by investigating the performance of the final design, and it is clear from investigation that blade profile for (NACA 634221) is best suited in terms of highest gliding ratio and lift force compared to other blade profiles studied.
