**11. Conclusion**

The chapter looked in-depth at the theory behind wind turbines, including solving equations and the various theories describing wind turbines in general. QBlade and XFoils were used to get a basic idea about the performance curves. Navier–Stokes equation was derived in rotational form, and the equations to solve for wind turbines by **Fluent** were listed. A brief look at the CAD design of the blade was given. Then, the complete procedure to perform an ANSYS simulation was explained, including **Fluent** Setup. Then, the results were presented graphically and numerically, and inferences were drawn. Finally, verification and validation were performed, verifying the simulation's correctness.

The main aim of the chapter was to provide the exact methodology to go from a theory in paper to results in **Fluent**. Every aspect of wind turbine design was covered in this chapter. The correctness of various theories and even QBlade & XFoils was compared to **Fluent**. Multiple simulations were performed in **Fluent**, with each 30 min simulation yielding a single row of tabular results. Finally, pitching inference was drawn for huge blades. Results were reported in a graphical and user-friendly manner without going into raw data. Verification and Validation, the most tricky and essential step, was successful for the simulation, and the errors were within bounds.
