Abstract
Renewable energy sources are increasingly highlighted as a solution to shortages of fossil fuels and to the degradation of socioeconomic and environmental aspects. Wind power, created by the movement of air masses, is an excellent example of clean energy and has been progressively used in the last decades as an energy source around the world. The evaluation of a region’s wind potential requires systematic work of collecting and analyzing data on the wind regime and its speed. This paper presents a study of the development of a computational model to analyzing data on the wind regime and its speed. This paper presents a study of the development of a computational model to analyze the internal boundary layer generated inside the atmospheric boundary layer, due to a neutral wind incident at a 90º cliff and caused by the surface unevenness and significant terrain’s roughness change. The study of boundary layers is extremely relevant in determining the position of wind turbines for power generation, the transmission capacity from airlines, and the spread of pollutants in the atmosphere, among others. To describe the flows, the mass conservation, the momentum equations and perfect gas are used. The computational model will be designed using the commercial software STAR-CCM+ and the results will be evaluated and compared with experimental data available in the literature.
