Aerosol Test Facility

Aerosol Test
Facility at
Research
Triangle Park
ADVANCING OUR
NATION'S SECURITY
THROUGH SCIENCE
EPA's Aerosol Test Facility (ATF) is
located in Research Triangle Park, North
Carolina. It is available to outside
agencies and businesses for research
into the behavior of aerosols
under controlled conditions.
Researchers, engineers, and
product designers can obtain
highly accurate data that will
form a scientifically sound basis
for their decisions.
The EPA Aerosol Test Facility includes
one of the largest aerosol wind tunnels
in the world. It has a cross-section of
4x4 meters and can be used with
full-sized adult manikins.
The ATF offers agencies or businesses
all the advantages of a large test facility
without the upfront investment in
equipment and continuing upgrades.
For additional information on this facility,
or on NHSRC products or tools, visit us at
www.epa.gov/nhsrc.

Using Our Facilities
EPA's campus in Research Triangle Park
is home to one of the world's largest
groups of scientists, engineers, policy
makers, and administrators dedicated
to understanding and solving
environmental problems. Specialty
laboratories and other unique
research resources can be used by
scientists and engineers in other
federal and state
agencies, academic
institutions, organizations,
and companies. Provisions
are in place to ensure
that EPA research will
not be affected by
any agreements with
other users. EPA's research
and development ATF may
be used for a variety of
research purposes. To find
out more about how your
agency, business, or
organization can participate,

The ATF's experimental and
computational fluid and particle
dynamics tools enable researchers
to determine and compare aerosol
residence time, velocity, and turbulence
characteristics at various points within
the test room.
Aerosol generation and sampling
Wind tunnels with separate human
exposure (low velocity) and
atmospheric exposure test sections
Particle Digital Image Velocimetry
(PDIV) and three-dimensional
Laser Doppler Velocimetry (LDV)
measurement
Experimental and numerical tools for
fluid and particle dynamics
The ATF has a heat exchanger and
humidification/dehumidification system
to ensure constant temperature and
humidity. Large filters are strategically
located in the test section, at the
safety screen, and just before the heat
exchanger. Doors are equipped with
Magnalock switches for safe and easy
release.
