Particle Image Velocimetry in Flickering Methane/Air Diffusion Flames

March 25, 2001
Author(s)
G Papadopoulos, Rodney A. Bryant, William M. Pitts
Phase-resolved measurements of the velocity field in acoustically forced, flickering laminar co-flowing methane/air diffusion flames have been made. Identical flames have been studied extensively in the past in order to characterize the effects of the

Thermal Agent Extinguishment of Two Types of Diffusion Flames

March 25, 2001
Author(s)
William M. Pitts, Rodney A. Bryant, Jiann C. Yang
The extinguishment of diffusion flames on two types of burners-an opposed-flow Tsuji burner and an axisymmetric burner with a surrounding coflow-by thermal agents has been investigated. Thermal agents are those that act primarily by extracting heat and

Toxic Yield

Author(s)
William M. Pitts
It is generally recognized that the vast majority of deaths associated with accidental enclosure fires are due to smoke inhalation. Older reviews of autopsy results suggested that the fraction was on the order of 2/3. In the United States there is evidence

Combustion Research Studies at the National Institute of Standards and Technology

January 1, 2000
Author(s)
Takashi Kashiwagi, William L. Grosshandler, Anthony P. Hamins, William M. Pitts, Cary Presser, Wing Tsang
The National Institute of Standards and Technology (NIST) is a federal agency within the Technology Administration of the Department of Commerce. NIST's primary mission is to develop and apply technology, measurements, and standards to promote economic

Scalar Dissipation in Axisymmetric Jets

November 21, 1999
Author(s)
William M. Pitts
Scalar dissipation, defined as twice the product of the molecular diffusion coefficient and the local gradient of the mixture fraction taken as a dot product with itself, characterizes molecular mixing rates in turbulent flows and has a central role in
