This paper investigates the effect that an additive had on the boiling performance of an R134a/polyolester lubricant (POE) mixture and an R123/naphthenic mineral oil mixture on a roughened, horizontal flat surface. Both pool boiling heat transfer data and
Approximately 20 % of fire fighters killed at structure fires over the past ten years have been as a result of structural collapse. Predicting a structural collapse is one of the most challenging tasks facing an incident commander at a fire scene. Usually
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 from two independent studies. The data span smooth tubes with inner diameters (D) from 3.3 mm to 11.6

NIST to develop a common, international vision for how a scientific foundation for performance-based fire safety design might be structured, which parts of the foundation are likely to be robust and where gaps are likely to exist into the foreseeable

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
