A series of measurements was made to characterize the structure a 1 m diameter methanol (CH3OH) pool fire steadily burning with constant lip height in quiescent environment. Time-averaged local gas-phase temperature were conducted using 50 μm diameter, Type S, bare wire, thermocouples bead that approximately spherical about 150 μm. The thermocouple signals corrected for radiative loss and therm...

With the continuous promotion of secondary water supply in urban high-rise buildings, corresponding difficulty management is also increasing. In order to facilitate management, enable users use tap that meets requirements national standard, and improve living standards residents, this paper analyzes design reconstruction, puts forward suggestions for its design, aiming further supply. Renovatio...

This paper describes the design of a full-scale experiment to measure the heat transfer from a large pool fire to an engulfed 1.2 m diameter, 2.54 cm wall thickness hollow cylindrical calorimeter. This work is focused at determining whether temperature measurements made on the interior calorimeter surface can be used with a one-dimensional inverse conduction solver to accurately determine the h...

A set of small-sized experiments were carried out at Texas A&M University's Brayton Fire Training Field (BFTF) to determine the radiative heat transfer of LNG pool fires. This set of experiments was designed to study how the heat feedback from the fire to the pool surface is subsequently distributed through the liquid volume. Burning rates of LNG pool fires are driven mainly by radiative heat t...

Infrared radiation is a type of electromagnetic radiation and invisible to human eyes. It is used widely in industrial, scientific, and medical applications. Pool fire is an emergent accident, which emits intense thermal radiation. In order to quantify the performance of water curtain fighting fire, a testing platform is built and experimental studies are carried out. An infrared imager is used...

Two prominent mechanisms proposed to structure biodiversity are niche-based ecological filtering and chance arrival of propagules from the species pool. Seed arrival is hypothesized to play a particularly strong role in high-diversity plant communities with large potential species pools and many rare species, but few studies have explored how seed arrival and local ecological filters interactiv...
