May 23, 2010
William and Ida Friday Center for Continuing Education
Chapel Hill, North Carolina, USA
Attendance is limited to 30 participants.
You may register by selecting the appropriate box on the Symposium Registration form.
Learning Objectives
The workshop attendees will be able to get a clear understanding of the following topics:
- influence of near-wake and far-wake regions on power generation
- statistical characteristics of the wind at the inlet to the wind farm
- measurement of wind
- atmospheric boundary layer and micrometeorology
- turbulence models for modeling wakes behind wind turbines
- wind energy’s place in national energy policy
- career opportunities in wind energy industry
Who Should Attend
All engineers who work in the wind energy industry will benefit from this course. In addition, the course will benefit graduate students who want to embark on a career in wind energy. Though the emphasis will be on the fluid mechanics side of wind farm, other aspects such as economics and finance of wind generation and career opportunities in the wind energy industry will be discussed.

Lecturers
1. Siva Parameswaran, professor and director of Computational Fluid Dynamics Laboratory, College of Engineering, Texas Tech University (email: siva.parameswaran@ttu.edu)
From 1989, his research was funded by automotive industries to develop computational models to predict external aerodynamics of passenger cars and pickup trucks. Recently, he is involved in modeling wind turbine wakes.
Dr. Parameswaran has given many short courses on CFD-related topics to industries and academia. He has given a two-day short course on “Computing Wind Noise” at Chrysler; conducted a one-day short course on “Turbulence Models for Multiphase Flows” for Halliburton engineers at Dallas; co-delivered a two-day short course on “Fundamentals and Applications of Computational Fluid Dynamics” at Tokyo Polytechnic University (TPU) for the Architecture and Wind Engineering graduate students in Tokyo; and organized a three-day workshop on “Future Trends in Sustainable Surface Transportation” at Coimbatore Institute of Technology, India for engineers from Indian auto industry.
2. Richard Walker, research associate, Wind Engineering Research Center, College of Engineering, Texas Tech University.
Richard (Rick) Walker is founder and principal of Sustainable Energy Strategies, Inc., which provides consulting services to utilities, developers of renewable energy projects, and large landowners. Currently, he is completing coursework toward a PhD in wind science engineering at Texas Tech University.
Mr. Walker has pioneered the development of wind energy in the southwest United States, having directly participated in the development of more than 1,400 megawatts of wind energy projects currently in operation in Texas or Oklahoma and another several hundred megawatts still in the development phase. His projects include the first utility-scale wind energy project in Texas and what will soon be the largest wind farm in the United States. In 2003, Mr. Walker was awarded the American Wind Energy Association’s award for outstanding contribution to the wind industry.
3. Sukanta Basu, Assistant Professor, Atmospheric Science Group, Department of Geosciences, Texas Tech University.
The primary research interests of Dr. Sukanta Basu are atmospheric boundary layer processes, turbulence modeling (large-eddy simulation), and wind power meteorology. He is a member of the American Association for Wind Engineering and also an elected member of the American Meteorological Society’s Boundary Layers and Turbulence Committee. Last year, Dr. Basu convened a session on wind power meteorology at the fall meeting of the American Geophysical Union. Over the past four years, Dr. Basu’s research has been funded by the National Science Foundation and the Texas Advanced Research Program.
At the end of the workshop, the participants will get an electronic copy of the lecture notes in pdf format.
If you have any question on the workshop you should send an email to Professor Siva Parameswaran, siva.parameswaran@ttu.edu .
Cost: US $125
The workshop registration fee includes morning light breakfast /refreshment break, buffet lunch, and afternoon refreshment break during each day.
