Greenhouse Gas Emissions and Dispersion #2. Comparison of FDS Predictions with Gas Velocity Measurements in the Exhaust Duct of a Stationary Source

April 25, 2013
Author(s)
Kuldeep R. Prasad, Kevin Li, Elizabeth F. Moore, Rodney A. Bryant, Aaron N. Johnson, James R. Whetstone
The burning of fossil fuels remains a major source of greenhouse gases responsible for global warming and climate change. In order to reduce greenhouse gas emissions, it is imperative to develop a capability to accurately measure these emissions from point

Characterizing Heat Release Rate Transients

April 26, 2012
Author(s)
Rodney A. Bryant, Erik L. Johnsson, George W. Mulholland
A series of experiments was performed to characterize the time response of a large-scale open calorimeter to square-wave pulses in terms of peak heat release rate, width of the peak, and conservation of energy. Quantitative heat release rate measurements

Comparison of Gas Velocity Measurements and CFD Predictions in the Exhaust Duct of a Stationary Source

July 13, 2011
Author(s)
Rodney A. Bryant, Olatunde B. Sanni, Elizabeth F. Moore, Robert P. Borthwick, Marco G. Fernandez, Iosif I. Shinder, Jiann C. Yang, Aaron N. Johnson
Two series of independent flow measurements were conducted for cross validation of flow velocity in the exhaust duct of the NIST Large Fire Laboratory. In the first series, two pressure measurement probe types, an S probe and a 3-D probe, were used to

A New Approach to Ventilation Measurements in Enclosure Fires

September 5, 2007
Author(s)
Rodney A. Bryant
The application of Stereoscopic Particle Image Velocimetry (SPIV) is a new approach to quantifying the ventilation in enclosure fires. SPIV is a non-intrusive optical measurement technique which measures the displacement of tracer particles in a flow. The
