NIST Station Nightclub Fire Investigation: Physical Simulation of the Fire

June 1, 2006
Author(s)
Daniel M. Madrzykowski, Nelson P. Bryner, Stephen Kerber
A fire occurred on the night of February 20, 2003, at The Station Nightclub located in West Warwick, Rhode Island. A band that was performing that night, during its performance, used pyrotechnics that ignited foam insulation lining the walls and part of

Fluid Dispensing and Dispersion

May 16, 2006
Author(s)
Jiann C. Yang, David R. Keyser
This paper is a condensed version of a chapter in the forthcoming Next Generation Program (NGP) final report edited by the authors. It summarizes the research conducted during the NGP program on fluid dispensing and dispersion within aircraft engine

Further Studies of Cup-Burner Flame Extinguishment.

May 16, 2006
Author(s)
F Takahashi, Gregory T. Linteris, Vishwanath R. Katta
The structure and extinguishment of heptane-air co-flow diffusion flames formed on a cup burner in normal earth gravity have been studied experimentally and computationally. A gaseous fire-extinguishing agent (CO2) was introduced gradually into a coflowing

Virtual Testing of Cement and Concrete

May 10, 2006
Author(s)
Dale P. Bentz, Edward J. Garboczi, Jeffrey W. Bullard, Chiara F. Ferraris, Nicos Martys, Paul E. Stutzman
Concrete is a unique multi-phase, random, complex, and composite material that provides both strength and impermeability to engineered structures. Unlike most construction materials, the properties of concrete continue to develop over time and in place an

An Improved Two-Phase Pressure Drop Correlation for 180 degrees Return Bends

May 1, 2006
Author(s)
Piotr A. Domanski, Christian Hermes
A new correlation for two-phase flow pressure drop in 180? return bends is proposed based on a total of 241 experimental data points for R-22 and R-410A. The data span smooth tubes with inner diameters (D) from 3.25 mm to 11.63 mm, bend radiuses (R) from 6

Chemical and Physical Characterization of Poly(p-phenylene benzobisoxazole) Fibers Used in Body Armor

May 1, 2006
Author(s)
Joannie W. Chin, E Byrd, Amanda L. Forster, Xiaohong Gu, Tinh Nguyen, Kirk D. Rice, Walter J. Rossiter Jr, S J. Scierka, John R. Sieber, Paul E. Stutzman, Li Piin Sung
Problems with the performance and durability of body armor based on poly(p-phenylene benzobisoxazole (PBO) fiber became apparent in the summer of 2003, when PBO-based body armor that was less than 8 months was penetrated by a bullet. Mechanical testing of

Evaluation of Aerodynamic Drag and Torque for External Tanks in Low Earth Orbit

May 1, 2006
Author(s)
William C. Stone, Christoph J. Witzgall
A numerical procedure is described in which the aerodynamic drag and torque in low Earth orbit are calculated for a prototype Space Shuttle external tank and its components, the "LO2" and "LH2" tanks, carrying liquid oxygen and hydrogen, respectively, for

Damping of Stay-Cable Vibrations: Modeling Overview and Design Implications

April 25, 2006
Author(s)
Joseph A. Main, Nicholas P. Jones
Dampers have become widely accepted as an effective means of stay-cable vibration suppression and have been implemented on numerous bridges around the world. Dampers are typically attached to the stays transversely near the anchorages, and different types

Engineered Infills for Concrete Barriers

April 3, 2006
Author(s)
Kenneth A. Snyder, C Langton, B Clark, Chiara C. Ferraris, J Dawson
Entombment may be considered as an option for decommissioning nuclear concrete structures so that licenses for facilities on which these structures reside may be terminated. Prior to entombment, the nuclear facility permanently ceases operations and spent
