Flow characterization of the UL Smoke Box and spot-type smoke detectors
… to characterize the flow fields with the UL Smoke Box and a spot type smoke detector within the test section of the smoke box. The proposed CFD model, designed to reflect the same measured conditions in the UL Smoke Box, was developed and validated through experimental velocity data using …

Mechanisms Of Smoke-Elicited Seed Germination Responses and Possible Candidate Active Compounds In Smoke
Smoke derived from burning plants has been well recognized as a seed germination promoter in a variety of plant species in many ecosystems. Previous studies revealed that smoke from legumes resulted in different germination responses compared to that from graminoids. However, the mechanisms for …

Rangefinding in Fire Smoke Environments
… environments contain varying levels of fire and smoke, both of which obstruct robotic perception sensors. In order to effectively use robots in fire environments, the issue of perception in the presence of smoke and fire needs to be addressed. The goal of this research was to address the problem …

Effectiveness of smoke barriers: pressurised stair enclosures
Stair Pressurisation Systems (SPS) are a form of smoke control used in many high-rise buildings. They are designed to keep smoke out of the stairwell so that occupants have a safe evacuation route during an emergency. Throughout the years, however, many within the Fire Engineering industry have …

Light scattering by smoke and nuisance aerosols
This study was aimed at discriminating between three classes of aerosols, namely those generated by flaming and non-flaming (smouldering and forced pyrolysis) fires as well as nuisance aerosols. This was undertaken using a scattering cross section based on the mass concentration of aerosols as …

Computer Aided Analysis of Smoke Stack Designs
… is to analyze the statics and dynamics of steel smoke stacks subject to excitation by aerodynamic forces. The wind loads experienced by smoke stacks arise from various phenomenon, the most prominent of which are static drag load, vortex shedding, and atmospheric turbulence. The nature of these …

A Wall of Smoke: Understanding the Drivers of the June 2023 Canadian Wildfire Smoke Event for New York City
… season was notable for its extent and the dense smoke it produced. Motivated by the resulting air quality impacts in the New York City region, we explore how the total particulate matter output from the Quebec fires influenced PM2.5 concentrations downstream in New York City. Using injection …

Smoke Aerosol Characterization for Spacecraft Fire Detection Systems
… There are a number of factors that affect the smoke particle size distribution in spacecraft fires. In low gravity, buoyant flow is negligible which causes particles to concentrate at the smoke source, increasing their residence time, and increasing the transport time to smoke detectors. …
