  • The Effect of Fuel Quantity and Location on Small Enclosure Fires

    Results from an experimental program undertaken to study the effect of fuel quantity and location on ethanol pool fires in the open and in a small enclosure (an ISO 9705 room) are compared with simulations using the Fire Dynamics Simulator version 4.03 (FDS4). The fuel in trays is placed at three locations (front, back, and center) within the room enclosure as well as directly under the ...

  • Invention of the Tire Shredder

    The process of vulcanizing rubber was discovered by Charles Goodyear (yes, you read that right) in 1839, and the development of rubber tires followed not long after (Source: Continental Truck). From there, it didn’t take long for worn-out tires to start piling up, and finding good ways to ...

  • Puyallup fire & rescue expands scope and effectiveness of emergency operations center team

    When the City of Puyallup (Washington) Fire & Rescue Department responds to emergency events, its first responders depend on timely coordination and efficient communication support from their colleagues at the city's Emergency Operations Center (EOC). The EOC team, in turn, depends on Essential Incident Master™ software from ESS to keep operations running smoothly. Essential Incident Master ...

  • Gypsum Board in Fire — Modeling and Experimental Validation

    The thermal behavior of a commercially widespread gypsum board (810 kg/m 3) under fire condition has been investigated. For this purpose two 12 mm thick gypsum boards are subjected to the standard fire ISO 834 and the temperature distribution within them is measured by means of thermocouples placed at different depths in the samples. The results hereof are used to validate a numerical model based ...

  • Tunnel fire smoke modelling for emergency management

    The current paper describes the investigation of parameters related to accidents in tunnels in the framework of the "Advanced Training System for Emergency Management" project, A-TEAM. On this basis, the flow field is investigated within tunnels, and its effects on fire development and smoke concentration fields for these emergency cases are reconstructed. This is achieved with the use ...

  • A system dynamics model of the fire department EMS in Taiwan

    Allocation of pre-hospital EMS (Emergency Medical Service) resources and effectiveness of emergency medical training are critical to patients. The demands for EMS are expected to increase in the future. By analysing the relationship between emergency response and the survival rates, the effectiveness of EMS resources and competence of personnel were evaluated. In other words, the current EMS ...

  • Analysis of fire behaviour simulations over Spain with WRF-FIRE

    Wildland fire spread and behaviour are complex phenomena owing to both the number of involved physico-chemical factors, and the non-linear relationship between variables. Spain is plagued by forest and brush fires every summer, when the extremely dry weather sets in along with high temperatures. The use of fire behaviour models requires the availability of high resolution environmental and fuel ...

  • `Explosion Modeling - A Blast from the Future,` published in Industrial Fire World, November

    Industrial facilities run like well oiled machines, keeping the pulse of the nation's economy moving at a steady clip. But on-site explosions slow this pulse, threatening workers'safety and jeopardizing production. Industry leaders know all too well the devastating effects that explosions can have on a facility. In its 1999 Process Safety Performance Measurement report, the American Petroleum ...

  • Modeling Prescribed Surface-Fire Regimes for Pinus strobus Conservation

    Abstract: We developed a simple model of  Pinus strobus L. stand dynamics to compare the impacts of different temporal arrangements of surface fires designed to reflect the application of fire as both an essential ecosystem process (natural fire) and as an efficient means of producing specific habitat features or other values (optimal fire). We used a stochastic simulation model of ...


  • Fire systems engineering case study

    General fire safety in England and Wales is delivered through compliance with the Regulatory Reform (Fire Safety) Order 2005. By virtue of this Order, the responsible person should carry out a fire risk assessment on their premises, implement appropriate fire precautionary and protection measures, and maintain a fire management plan. The main purpose of the order is to prevent fire, minimise risk ...

  • Application of geographical information systems and FARSITE in fire spread modelling

    Wildfires are a perennial problem in the Northwest of USA. Wallowa Whitman National Forest fires are quite frequent as a result forest completes between 10,000 and 15,000 acres of burning in a year. According to research, it was reported that the study area experienced fires from 1970 to 2006 with total burning of 149 fires and total burnt area of 7,583 hectares per year which observed to be ...

  • Fire prevention strategies, storm cleanup

    WHEN IT comes to the importance of clearing dead and diseased trees as a fire prevention step, Wayne Williams of San Diego County, California is living (and breathing) it. “I was walking around the fire zone, and where residents had cleared spaces around their homes, the house was usually saved,” says Williams. “Houses without a firebreak, or on a ridge (where fire can leap out of a canyon), were ...

  • A novel approach for modelling of NOx emission reduction in a tangentially fired coal boiler

    In this research paper, predictive modelling of NOx emission of a 210 MW capacity pulverised coal–fired boiler and combustion parameter optimisation to reduce NOx emission in flue gas is proposed. The effects of oxygen concentration in flue gas, coal properties, coal flow, boiler load, air distribution scheme, flue gas outlet temperature and nozzle tilt were studied. The data collected from ...

  • Evaluation of CFD Modeling Methods for Fire-induced Airflow in a Room

    Methods for exploiting the technique of computational fluid dynamics (CFD) to model fires and the associated fundamental processes of combustion and radiation are appraised by applying the CFD model JASMINE to simulate the fire-induced airflow in a room-sized compartment. For a systematic evaluation of these methods describing the fundamental processes and the associated mathematical formulation, ...

  • Swedish solution for high-rise building fires

    Swedish fire fighting nozzle specialists, Unifire AB, have developed what may very well usher in a new era in fire fighting: a fully automatic fire detection and extinguishing system, called FlameRanger. The system, according to Unifire, is capable of detecting and extinguishing a fire in seconds of its breaking out, with minimal use of water, and without any human intervention required. Unifire ...

  • Field Model Analysis and Experimental Assessment of Fire Severity and Smoke Movement in a Partitioned and a Non-partitioned Dwelling Unit

    Inter-compartment smoke spread in a dwelling unit is greatly impeded by the presence of partition walls. For the same fire load and floor area, smoke movement and associated fire severity for a non-partitioned (NP) unit are different from those of a partitioned (PT) unit. To study the smoke movement and gas temperature evolution, computational fluid dynamics (CFD) analysis is carried out for a ...

  • Using plume rise schemes to model highly buoyant plumes from large fires

    The atmospheric dispersion model Numerical Atmospheric-dispersion Modelling Environment (NAME) is used to simulate the smoke plume from the explosion at the Buncefield oil depot. Simple modelling, in which the plume rise is included through an effective elevated source term, captures the transport and spread of the plume well. More complex modelling, using the NAME plume rise scheme, ...

  • Effect of the radiation heat loss on propagation of the spherical flame through premixed coal dust

    An analytical study has been conducted to investigate the effect of radiation heat loss on the spherical flame propagation in coal–dust clouds. This research can be valuable in the development of alternative fuels; and it can be used by the fire safety and control industry. The model includes the evaporation of the volatile matter of dust particles into a known gaseous fuel (methane) and the ...
