Structure Separation Experiments Phase 1 Preliminary Test Plan

May 26, 2021
Author(s)
Alexander Maranghides, Shonali Nazare, Eric Link, Kuldeep Prasad, Matthew Hoehler, Matthew Bundy, Steven Hawks, Frank Bigelow, William (Ruddy) Mell, Anthony Bova, Derek McNamara, Tom Milac, Daniel Gorham, Faraz Hedayati, Bob Raymer, Frank Frievalt, William Walton
The primary objective of this project is to assess structure-to-structure fire spread for structures located in the Wildland Urban Interface (WUI). Full-scale fire experiments will be conducted in which various types of structures (sources of fire) will be

Wintertime CO2, CH4 and CO emissions estimation for the Washington DC / Baltimore metropolitan area using an inverse modeling technique

February 11, 2020
Author(s)
Israel Lopez Coto, Xinrong Ren, Olivia E. Salmon, Anna Karion, Paul B. Shepson, Russell R. Dickerson, Ariel Stein, Kuldeep R. Prasad, James R. Whetstone
Since greenhouse gas mitigation efforts are being mostly implemented in cities, the ability to quantify emission trends for urban environments is of paramount importance. However, previous aircraft work has indicated large daily variability in the results

Evaluation of WRF-Chem Simulated Carbon Dioxide Atmospheric Transport and Emissions in the Baltimore / Washington Metropolitan Area

November 10, 2018
Author(s)
Cory R. Martin, Ning Zeng, Anna Karion, Kimberly L. Mueller, Subhomoy Ghosh, Israel Lopez Coto, Kevin Gurney, Tomohiro Oda, Kuldeep R. Prasad, Yun Liu, Russell R. Dickerson, James R. Whetstone
Urban areas are major sources of carbon dioxide (CO2) emissions, contributing to the increase in global concentrations and leading to concerns about Earth's future climate. In recent years, several urban testbeds have been implemented to improve and

Chapter 2 : Failure Modes, Likelihood, and Consequences

January 20, 2018
Author(s)
Kuldeep R. Prasad
The general purpose of underground gas storage (UGS) is to meet varying demand for natural gas (methane, CH4) over daily to seasonal time scales in the face of constant rate gas production and limited pipeline transport capacity. In California, UGS is used

Tower based measurement network design for the North East Corridor project

May 17, 2017
Author(s)
Israel Lopez Coto, Subhomoy Ghosh, Kuldeep R. Prasad, James R. Whetstone
The North-East Corridor project aims to use a top-down inversion method to quantify sources of Greenhouse Gas (GHG) emissions in the urban areas of, in the first phase, Washington DC and Baltimore at approximately 1km2 resolutions. Since inversion methods

Fire Structure Interface for the World Trade Center Towers

February 19, 2017
Author(s)
Kuldeep Prasad, Howard R. Baum
The collapse of the World Trade Center towers on September 11, 2001, resulting from a combination of aircraft impact damage and subsequent fires, was studied as part of the Federal Building and Fire Safety Investigation of the World Trade Center Disaster

Localized Ignition and Subsequent Flame Spread Over Solid Fuels in Microgravity

February 19, 2017
Author(s)
Takashi Kashiwagi, Y N. Nakamura, Kuldeep Prasad, Howard R. Baum, S L. Olson, O -. Fujita, K K. Nishizawa, K. Ito
Ignition and subsequent flame spread over a paper sample and a PMMA sheet in microgravity are studied experimentally and theoretically. New results obtained during last two years are described.

Real Fire Performance of Partition Assemblies: Insulated and Non-Insulated Assemblies

February 19, 2017
Author(s)
Samuel Manzello, Richard Gann, S R. Kukuck, Kuldeep Prasad, Walter W. Jones
Two gypsum wall assemblies were exposed to intense real-scale compartment fires, from the time of ignition to beyond flashover. The construction of each assembly (2.44 m by 2.44 m) was identical, with the exception that one of the wall assemblies was

Simulating Fire Dynamics and Thermal Response of Structural Elements

February 19, 2017
Author(s)
Kuldeep Prasad, Howard R. Baum
Simulation of the effects of severe fires on the structural integrity of builings requires a close coupling between the gas phase energy release andtransport phenomena and the stress analysis in the load bearing materials. The connection between the two is

Structural Analysis of a High-Rise Composite Frame Exposed to Fire

February 19, 2017
Author(s)
Dat Duthinh, Kuldeep Prasad
This paper presents a simplified, planar analysis of World Trade Center Tower 1 (WTC1), starting from a computer simulation of the fire using computational fluid dynamics, and progressing through a thermal and a structural analysis of the damaged structure

Greenhouse Gas Emissions and Dispersion 3. Reducing Uncertainty in Estimating Source Strength and Location through Plume Inversion Models

September 30, 2015
Author(s)
Kuldeep R. Prasad, Adam L. Pintar, Heming Hu, Israel Lopez Coto, Dennis T. Ngo, James R. Whetstone
Recent development of accurate instruments for measuring greenhouse gas concentrations and the ability to mount them in ground based vehicles has provided an opportunity to make temporally and spatially resolved measurements in the vicinity of suspected
