Selecting the correct airfoil section for the blade is essential. The angle of attack and how it impacts lift and drag forces, such as whether it creates high lift and low drag or vice versa, are crucial aspects that define the system's performance. The artwork that was exhibited was inspired by this. The study's major goal was to compare the NACA 2412, NACA 4412, NACA 23012, and NACA 23112 airfoils at various angles of attack while keeping the Reynolds number constant. The geometry and analysis were done in Ansys-Fluent, and the CFD study used the SST K-w model. Calculations were done from a variety of attack angles. For the computational domain, an unstructured mesh with inflation and sphere of effect was selected, taking care of the grid refinement surrounding the airfoil to encapsulate the boundary layer approach. The results of the CFD simulation are very consistent with those obtained by experimentation, showing that CFD analysis is a reliable substitute for experimental methods.
