961. A BBGKY-based density gradient approximation of interparticle forces: Application for discrete Boltzman methods
Topic: Building and Fire Research
Published: 10/26/2005
Author: Nicos Martys
Abstract: The force term accounting for intermolecular interactions, with application to discrete Boltzmann simulation methods, is derived directly using a density gradient expansion of the BBGKY collision operator. It is shown that previous calculations, bas ...

962. Cross-Property Correlations and Permeability Estimation in Sandstone
Topic: Building and Fire Research
Published: 10/26/2005
Authors: C H Arns, M A Knackstedt, Nicos Martys
Abstract: 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 foc ...

963. Dissipation of Oxygen From Outward Leak of Closed Circuit Breathing Device
Topic: Building and Fire Research
Published: 10/18/2005
Authors: Kathryn M Butler, Rodney A Bryant, J G Kovac
Abstract: 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. Fir ...

965. Basis for Appropriate Safety Levels for Tall Buildings.
Topic: Building and Fire Research
Published: 10/16/2005
Author: Richard W. Bukowski
Abstract: 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 asso ...

966. Challenges to Fire Safety in Tall Buildings.
Topic: Building and Fire Research
Published: 10/16/2005
Author: Richard George Gann
Abstract: 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 requi ...

967. Emergency Egress and Access.
Topic: Building and Fire Research
Published: 10/16/2005
Author: Jason D Averill
Abstract: 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 ques ...

968. Federal Building and Fire Safety Investigation of the World Trade Center Disaster.
Topic: Building and Fire Research
Published: 10/16/2005
Author: S S Sunder
Abstract: A major scientifically based investigation of the WTC disaster was completed recently by NIST. The investigations establish the technical causes of building failures and evaluate the technical aspects of response and evacuation. NIST is a neutral inv ...

969. Towards a Methodology for the Characterization of Fire Protection Materials With Respect to Thermal Performance Models
Topic: Building and Fire Research
Published: 10/12/2005
Authors: Dale P Bentz, Kuldeep R Prasad, Jiann C Yang
Abstract: A methodology is proposed for the characterization of fire protection materials with respect to thermal performance models. Typically in these models, materials are characterized by their densities, heat capacities, thermal conductivities, and any e ...

970. Low Temperature Calorimetry Studies of Hydrating Portland Cement Pastes
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7267
Topic: Building and Fire Research
Published: 10/5/2005
Author: Dale P Bentz
Abstract: 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 t ...
