Cross-Property Correlations and Permeability Estimation in Sandstone

October 26, 2005
Author(s)
C H. Arns, M A. Knackstedt, Nicos Martys
Results from a numerical study examining the cross-property correlations linking fluid permeability to conductive properties and to a number of pore size parameters based on 3D digitized images of sedimentary rock are presented. In particular we focus on

Dissipation of Oxygen From Outward Leak of Closed Circuit Breathing Device

October 18, 2005
Author(s)
Kathryn M. Butler, Rodney A. Bryant, J G. Kovac
Closed circuit breathing devices recycle exhaled air after scrubbing carbon dioxide and adding make-up oxygen from a tank of pure oxygen. Use of this equipment allows first responders to work for up to four hours without swapping out cylinders

Basis for Appropriate Safety Levels for Tall Buildings.

October 16, 2005
Author(s)
Richard W. Bukowski
Safety levels are a public policy decision made by regulators and not the technical community. It is appropriate for the technical community to suggest technical justification for safety levels, performance levels that can be achieved, and their associated

Challenges to Fire Safety in Tall Buildings.

October 16, 2005
Author(s)
Richard G. Gann
In order to increase the chances of survival during a fire emergency, the time available for a person to leave the danger zone must be longer than the time needed to make the escape. For tall buildings, providing time for people to reach safety requires

Emergency Egress and Access.

October 16, 2005
Author(s)
Jason D. Averill
Tall buildings present a unique and challenging egress environment. The very aspect ratio which makes tall buildings economically desirable accentuates the impact of egress and other building systems. Further, recent events have raised important questions

Low Temperature Calorimetry Studies of Hydrating Portland Cement Pastes

October 5, 2005
Author(s)
Dale P. Bentz
This report presents nearly 200 low temperature calorimetry (LTC) scans performed on hydrating portland cement pastes between 2002 and 2005. Because the LTC scans provide valuable information on the percolation of various size pore networks within the

The Application of MatML to Contaminant Emissions Data

October 1, 2005
Author(s)
E F. Begley, Cynthia H. Reed
Standard data formats are generally employed because they save time and money by promoting interoperability, i.e., facilitating data exchange and preserving information for re-use, and are available for a wide variety of business, scientific, and

Airtightness of Commercial Buildings in the United States

September 21, 2005
Author(s)
Steven J. Emmerich, Andrew K. Persily
In 1998, Persily published a review of commercial and institutional building airtightness data that found significant levels of air leakage and debunked the myth of the airtight commercial building. This paper updates the earlier analysis for the U.S. by

Energy Balance in a Large Compartment Fire. (POSTER ABSTRACTS)

September 18, 2005
Author(s)
Anthony P. Hamins, Erik L. Johnsson, Michelle K. Donnelly
The experiments described here were part of an international collaborative project to assess and validate fire computer codes for nuclear power plant applications. Understanding the distribution of energy released by a fire is important for testing the

Experiments and Modeling of Unprotected Structural Steel Elements Exposed to a Fire

September 18, 2005
Author(s)
Anthony P. Hamins, Kevin B. McGrattan, Kuldeep R. Prasad, Alexander Maranghides, Therese P. McAllister
A large-scale fire experiment was conducted to assess the accuracy of a combination of gas and solid-phase models designed to predict the temperatures of structural steel elements exposed to a fire. The experiment involved a 2 MW heptane spray fire in a

Simulating Fire Effects on Complex Building Structures.

September 18, 2005
Author(s)
Howard R. Baum
The purpose of this lecture is to assess the current state of our ability to simulate the consequences of a fire in a large building, and suggest some areas where improvement is needed. Attention is focused on the coupling of fire dynamics simulations and

Challenges in Characterizing Sealant

September 14, 2005
Author(s)
Christopher C. White, Donald L. Hunston
Sealant is one of the very few major consumer products valued primarily for its rheological and adhesive properties. While, these materials may appear to be simple elastic solids, upon further examination, their behavior can be extremely complex. In this
