A Data-Driven Predictor of the Discharge Coefficient of Orifice Plates

April 1, 2015
Author(s)
James R. Whetstone, Antonio M. Possolo
We have developed a new functional relationship to predict the value of the discharge coefficient of an orifice plate used to measure volumetric flow rate in cylindrical pipes, as a function of the beta ratio of the orifice and pipe combination, and of the

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

Greenhouse Gas Emissions and Dispersion 1. Optimum placement of gas inlets on a building rooftop for the measurement of greenhouse gas concentrations

April 22, 2013
Author(s)
Kuldeep R. Prasad, Anthony Bova, James R. Whetstone, Elena Novakovskaia
Inverse atmospheric dispersion models are used to provide measurement-based, or “topdown”, estimates of greenhouse gas (GHG) emissions for comparison with input-based, or “bottom-up”, estimates. To minimize uncertainty, inverse estimates require accurate

Construction of a High Power OPO Laser system for Differential Absorption LIDAR

September 13, 2011
Author(s)
Kevin O. Douglass, Stephen E. Maxwell, David F. Plusquellic, Joseph T. Hodges, Roger D. van Zee, Daniel V. Samarov, James R. Whetstone
Our goal is to develop and characterize optical measurement technology to enable accurate quantification of greenhouse-gas emissions to meet the needs of industry and regulators. A 1064 nm pumped high energy optical parametric oscillator (OPO) operating

Examination of United States Carbon Dioxide Emission Databases

June 10, 2011
Author(s)
Robert P. Borthwick, James Whetstone, Jiann C. Yang, Antonio Possolo
This paper compared carbon dioxide emissions from plants obtained in two ways, first from the US Department of Energy, Energy Information Administration EIA-767 database and EIA-1605 Greenhouse Gas Reporting Program guidelines and second from the U.S. Envi

A Second-Generation NIST Gravimetric Hygrometer

April 1, 2010
Author(s)
Christopher W. Meyer, Joseph T. Hodges, Gregory E. Scace, James R. Whetstone, R W. Hyland
A second-generation primary hygrometer has been completed at the National Institute of Standards and Technology (NIST). A gravimetric hygrometer measures humidity by separating the water from the carrier gas using desiccants and afterwards independently

Automated Continuous-Flow Gravimetric Hygrometer as a Primary Humidity Standard

May 1, 2008
Author(s)
Christopher W. Meyer, Joseph T. Hodges, R W. Hyland, Gregory E. Scace, J Valencia-Rodriguez, James R. Whetstone
A new primary gravimetric hygrometer has been completed at the National Institute of Standards and Technology (NIST). This apparatus determines the humidity in a steadily flowing gas stream by first separating the water from the carrier gas using
