To combat climate change, renewable energy will become increasingly important in the immediate future. Second only to energy efficiency measures in its potential to reduce carbon emissions, wind energy is already, and will continue to be, an important player in the field. The study of wind turbines presupposes the study of turbulence. To avoid the expensive, cumbersome, and slow process of experimental study, physically-accurate simulations can be built. This thesis aimed to build such a simulation utilizing the most recent k-ω turbulence model developed by D. C. Wilcox (2006). Along the way, the thesis develops the turbulence theory necessary to understand and apply the turbulence model.
