Clarkson University's Goodarz Ahmadi Co-Authors Book on Air Particle Movement

Computer modeling can be used to remove germs and pollutants from indoor air, according to Goodarz Ahmadi, dean of the Wallace H. Coulter School of Engineering at Clarkson University.
 
Goodarz Ahmadi, dean of the Wallace H. Coulter School of Engineering at Clarkson UniversityAhmadi, a professor of mechanical and aeronautical engineering, has co-authored Computational Fluid and Particle Dynamics in the Human Respiratory System, which explains the science behind tracking particles in airflow through a room and into the respiratory tract.

The book contains best-practice guidelines students and scientists can use to establish high-quality computer models and simulations, as well as an introduction to the physics of the respiratory system.
 
“The final goal is to try to understand how to remove those particles so fewer pollutants get into the human body,” Ahmadi said. “You want to have a healthy building. You want to have it be healthy so that germs are not spread and people don’t get sick or catch colds.”
 
Ahmadi worked on the book for several years and has taught courses at Clarkson on using computer models to track particles in airflow for the last three decades. He completed much of the book on nights, weekends and during a research trip he took to Australia two years ago.

Ahmadi examined CT Scans of nasal cavities, as well as a cast of a lung donated to science, in order to study the journey of an air particle once it enters the body. 
 
“Somehow God plants this very complicated upper respiratory passageway with its turns and twists to capture particles,” Ahmadi said of the nose. “It’s designed perfectly.”
 
Jinyan Tu and Kiao Inthavong co-wrote the book with Ahmadi. Both are professors of mechanical and manufacturing engineering at RMIT University in Bundoora, Victoria, Australia.
 
Ahmadi has authored more than 520 papers in archival journals, in addition to two earlier books and more than 1,000 papers in national and international conference proceedings. He has also given more than 150 keynote lectures and invited seminars worldwide.

He is on the editorial advisory board of seven technical journals and is a fellow of ASME, ISME and ISCE. He was also a Senior Research Associate at National Energy Technology Laboratory (NETL). More information can be found on his research Web site at http://clarkson.edu/projects/fluidflow.
 
Clarkson University launches leaders into the global economy. One in five alumni already leads as a CEO, VP or equivalent senior executive of a company. Located just outside the Adirondack Park in Potsdam, N.Y., Clarkson is a nationally recognized research university for undergraduates with select graduate programs in signature areas of academic excellence directed toward the world’s pressing issues. Through 50 rigorous programs of study in engineering, business, arts, sciences and health sciences, the entire learning-living community spans boundaries across disciplines, nations and cultures to build powers of observation, challenge the status quo, and connect discovery and engineering innovation with enterprise.
