Passenger Minivan Fire Tests. REPORT OF TEST FR 4012

December 1, 2001
Author(s)
D W. Stroup, Laurean A. DeLauter, James J. Lee, G Roadarmel
Two fire tests were conducted using a passenger minivan. The fire test scenarios were selected as part of a fire investigation being conducted by the U.S. Department of Treasury s Bureau of Alcohol, Tobacco, and Firearms. Heat release rate was determined

Suppression of Fires Exposed to an External Radiant Flux

December 1, 2001
Author(s)
Michelle K. Donnelly, William L. Grosshandler
When materials are burning in the presence of a continuous, external energy source, they are often more difficult to extinguish and may require an increase in suppression agent to extinguish the fire. This situation could exist for class C fires involving

Towards a Global Agenda for Fire Research

December 1, 2001
Author(s)
J E. Snell
The Forum for International Cooperation on Fire Research, FORUM, was established about 14 years ago as an informal organization to provide a means for sharing on mutual issues and needs, communication, and cooperation among the world's leaders of fire

CFD Modeling and Comparison with Data for the NIST Reference Spray Combustor

November 1, 2001
Author(s)
D S. Crocker, J F. Widmann, Cary Presser
Validation of computational fluid dynamics (CFD) predictions for spray combustion application has been a challenging task due to difficulties in both modeling and experimental measurements. However, validation is considered to be an essential exercise for

Drying/Hydration in Cement Pastes During Curing

November 1, 2001
Author(s)
Dale P. Bentz, K K. Hansen, H D. Madsen, F A. Vallee, E J. Griesel
As concrete cures in the field, there is a constant competition for the mixing water between evaporation and hydration processes. Understanding the mechanisms of water movement in the drying/hydrating cement paste is critical for designing curing systems

Effect of Aluminum Flake Orientation on Coating Appearance

November 1, 2001
Author(s)
Li Piin Sung, Maria E. Nadal, M E. McKnight, Egon Marx, R Dutruc-Rosset, B Laurenti
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using

Fire Dynamics Simulator (Version 2) -- User's Guide

November 1, 2001
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) modelof fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

Fire Dynamics Simulator (Version 3): Technical Reference Guide (NISTIR 6783)

November 1, 2001
Author(s)
Kevin B. McGrattan, Howard R. Baum, Ronald G. Rehm, Anthony P. Hamins, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The equations described in this document are a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an emphasis on

Fire Dynamics Simulator (Version 3): User's Guide (NISTIR 6784)

November 1, 2001
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

Physical Degradation Of Polymeric Coating Surfaces Using Atomic Force Microscopy

November 1, 2001
Author(s)
Mark R. VanLandingham, M Giraud, Tinh Nguyen, Walter E. Byrd, Jonathan W. Martin
Atomic force microscopy (AFM) and Fourier Transform Infrared (FTIR) spectroscopy were used to monitor physical and chemical changes, respectively, in acrylic melamine coatings caused by exposure to a 50 C, 70 % relative humidity environment with and

Strength and Ductility of Concrete Beams Reinforced with Carbon FRP and Steel

November 1, 2001
Author(s)
Dat Duthinh, M A. Starnes
Seven concrete beams reinforced internally with steel and externally with carbon fiber-reinforced polymers (FRP) applied after the concrete had cracked were tested under four-point bending. Results show that FRP is very effective for flexural strengthening

Strength of an Interlocking FRP Connection

November 1, 2001
Author(s)
Dat Duthinh, K K. Bajpai
The strength of an interlocking fiber-reinforced polymer (FRP) connection was measured in bending, and in-plane and out-of-plane shear. This connection allows the rapid assembly of FRP panels into houses, and can be used in interlocking mode only, or

Ultraviolet Chambers Based on Integrating Spheres for Use In Artificial Weathering

November 1, 2001
Author(s)
Joannie W. Chin, E Byrd, N Embree, Jonathan W. Martin, J D. Tate
Laboratory ultraviolet (UV) chambers are widely used to obtain weathering data for a wide range of commercial polymer products including coatings, textiles, elastomers, plastics and polymeric composites. Although numerous improvements have been made in the
