This paper describes the fabrication of a guarded-hot-plate apparatus suitable for determining the steady-state thermal transmission properties of insulation specimens from 90 K to 900 K in a controlled gas atmosphere from 10 -5 kPa to 105 kPa. The long
The U.S. Department of Housing and Urban Development (HUD) has identified a need to improve urban housing conditions to protect children s health through its Healthy Homes Initiative (HHI). One critical area within this program is to address a wide range

Improvements have been made to the combustion and radiation routines of a large eddy simulation fire model maintained by the National Institute of Standards and Technology. The combustion is based on a single transport equation for the mixture fraction
This user s manual provides updated documentation and computer program listings for version 3.0 of the three-dimensional cement hydration and microstructure development model (CEMHYD3D) developed at the National Institute of Standards and Technology
This paper investigates the effect that the bulk lubricant concentration has on the non-adiabatic lubricant excess surface density on a roughened, horizontal flat pool-boiling surface. Both pool boiling heat transfer data and lubricant excess surface

A series of measurements has been carried out to quantify the thermal properties of materials used to fabricate fire fighters' thermal protective clothing. The thermal property measurements chosen have direct application for use in heat transfer
The guarded hot plate (GHP) apparatus is the most common type of absolute apparatus for measurement of the thermal transmission properties of thermal insulation. As the name implies, the hot meter plate is surrounded by a coplanar guard plate, separated by
The National Bureau of Standards (now the National Institute of Standards and Technology (NIST)) pioneered the use of circular line-heat-sources in guarded hot plate (GHP) apparatus, the most common type of absolute apparatus for measurement of the thermal

Experimental data were taken to examine R-410A mass flow rate characteristics through short tube restrictors at upstream pressures approaching the critical point. Four short tube restrictors were tested by varying upstream pressure from 2619 kPa to 4551

Black PMMA was burned in the cone calorimeter in two orientations (horizontal and vertical), at imposed radiant heat fluxes of (0, 5, 10, 25, 50, and 75) kW/m2, and the visual appearance, flame size, heat release rate, and mass loss rate were recorded

Trialkylimidazolium-tetrafluoroborate, (IM) compatibilized, multiwalled carbon nanotubes (MWNT) were used to prepare well dispersed polystyrene (PS) IM-MWNT nanocomposites via melt extrusion. Quantitative TEM image analysis revealed superior dispersion of

This workshop provided a forum to discuss the strategies, technologies, procedures, best practices, research and development that can significantly improve thermal imaging technology. The goal of the workshop was to identify barriers that impede advances
There is a high probability that gases or liquids with high boiling points, higher than that of Halon 1301, will be required to provide fire protection in engine nacelles. In such complex flow environments, the performance of the suppression agent will

Researchers at the National Institute of Standards and Technology (NIST) have measured the performance of a residential fuel cell system when subjected to various environmental and load conditions. The system, which uses natural gas as its source fuel, is
This paper presents a comparable evaluation of R600a (isobutane), R290 (propane), R134a, R22, R410A, and R32 in an optimized finned-tube evaporator, and analyzes the impact of evaporator effects on the system coefficient of performance (COP). The study
This paper is an enhanced version of the paper, PERFORMANCE OF HC AND HFC REFRIGERANTS IN A FINNED-TUBE EVAPORATOR AND ITS EFFECT ON SYSTEM EFFICIENCY approved by WERB a few months ago and was presented at the Natural Refrigerants Conference. There are no
The effect of film thickness, substrate hole diameter, and shaft tip diameter on the applied strain energy release rate, G, of a thin film was measured using the shaft-loaded blister test. Test specimens consisted of plies of Kapton pressure sensitive

An experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed for the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The
The curve-based method was evaluated based on performance predictions for nine mixed systems, which were also tested by an independent testing laboratory. Capacity predictions were within 5% of the tested values for six of nine mixed systems, and four of
Society is increasingly concerned about the implications of manufactured products for the environment, public health, and future costs. How does a product affect Global Warming, Smog, Fossil Fuel Depletion, and Human Toxicity? How about its Costs over Time
