In situ monitoring of atmospheric methane using a dense network in the Northeastern U.S.

February 28, 2013
Author(s)
Kuldeep R. Prasad, Elena Novakovskaia, Marc Fischer, Chris Sloop
Methane (CH4) is one of the major greenhouse gases with a CO2–relative global warming potential above 20 over a 100-year period (IPCC TAR). Global average concentration of this tracer in Earth's atmosphere is increasing due to widely spread surface sources

The National Institute of Standards and Technology (NIST) conducted an extensive investigation of the collapse of the three tall World Trade Center (WTC) buildings. This paper describes the reconstruction of the fires, the thermal environment they created

Helium Dispersion in an Attached Single-Car Residential Garage with and Without Vehicle

October 2, 2012
Author(s)
William M. Pitts, Jiann C. Yang, Marco G. Fernandez, Kuldeep R. Prasad
The dispersion and loss of helium inside a single-car residential garage attached to a single-family house was experimentally characterized by recording time-resolved helium concentrations at multiple locations in the garage and at a single location in the

MEASUREMENTS OF EFFECTIVE DIFFUSION COEFFICIENT OF HELIUM AND HYDROGEN THROUGH GYPSUM

September 14, 2011
Author(s)
Jiann Yang, William M. Pitts, Marco Fernandez, Kuldeep Prasad
An experimental apparatus, which was based on the ¿-scale garage previously used for studying helium release and dispersion in our laboratory, was used to obtain effective diffusion coefficients of helium and hydrogen (released as forming gas for safety

High Pressure Release and Dispersion of Hydrogen in a Partially Enclosed Compartment

March 1, 2011
Author(s)
Kuldeep R. Prasad, Thomas G. Cleary, William M. Pitts, Jiann C. Yang
The study of compressed hydrogen release from high-pressure storage systems has practical application for hydrogen and fuel cell technologies. Such releases may occur either due to accidental damage to a storage tank or connecting piping, or direct PRD
