Purdue University has made recent strides towards advancing the efficiency of wind energy capture. These efforts were made in large part by Douglas E. Adams, the prior Kenninger Professor of Renewable Energy and Power Systems at Purdue University, along with two computer science professors, Jan Vitek, Ananth Grama and Suresh Jagannathan. Adams along with other Purdue colleagues received a $1.6 million three-year grant from the National Science Foundation’s Division of Computer and Network Systems to perform wind projects with purpose to improve the performance of “smart” wind turbines and wind farms (Purdue Engineering Impact Magazine). The primary aim of the smart wind turbine is to reduce to unharnessed energy that results from the wake effect. Wind turbines extract energy from the wind to produce electricity thus the wind leaving the turbine has a lower energy content than that of the original gust of wind. This exiting wind has a significantly reduced speed and is turbulent; this is what is considered the wake of the turbine. When this wake converges with the swept area of a downwind turbine, it brings about two consequences. First, there is a reduction is wind speed passing through the turbine; therefore, less energy is produced within the wind farm. Secondly, the increase in turbulence from the wake will likely cause greater dynamic mechanical loading on the turbine which threatens the life span of the machine (Gonzalez-Longatt, Wall, and Terzija). The…
