PURPOSE
The Texas Tech University Wind Science and Engineering Research
Center uses over 35 years of multidisciplinary research into the effects
of windstorms on the built environment and people to capitalize on
the beneficial effects of wind. The center performs advanced and
innovative multi-disciplinary, wind-related research including wind
flow characterization, wind structural engineering and wind power
systems. In 2007, the research center and Texas Tech University
established the first multidisciplinary doctoral degree in the nation,
providing students with the opportunity to integrate various aspects of
the wind science and engineering program into one graduate degree.

RESEARCH FOCUS                                                                                                    on the Texas Tech 200 meter Data Acquisition Tower

Wind Power Systems Research is focused on full-scale testing, characterization, system optimization, and demonstration of grid-connected
utility-scale wind turbines designed for wind regimes such as those of the Southern Great Plains and integrated wind-water desalination
systems.
