TERRAIN MODELING FOR WIND ENERGY

President Obama has set an aggressive goal of nationally utilizing 20% wind energy by 2030. For the nation to reach this goal wind energy must be assessable across the nation. Wind energy farms are expected to provide most of this energy however, energy transmission losses may limit wind energy provided to urban areas. Energy transmission losses are significantly reduced by placing the wind turbines close to the energy consumer. Low cost turbines can be installed on roof tops and in the yard of urban consumers. However, terrain obstacles such as buildings and trees can significantly reduce available wind energy. In this simple example it was determined that a interference with tree and building roof top reduced available wind turbine air supply by 12%. CFD terrain analysis can be used to determine the best location for a wind turbine in an urban environment.
