    In-situ measurements of toxic gases in a tube furnace2009Report (Refereed)
    Abstract [en]

    Infrared Polarization Spectroscopy (IRPS) was used to detect and quantify HCl and HCN in an 800 mm long tube furnace. Pieces of a PVC-carpet or pellets of nylon 6,6 were continuously fed into the furnace producing a heavy smoke. This constitutes a very harsh environment from a diagnostic point of view due to the high smoke density and relatively long length of the furnace. Despite this it was possible to quantify HCl and HCN concentrations in the smoke down to a levels of 50 ppm using IRPS. The explanation for this success is twofold. Firstly the IRPS method is inherently almost noise free due to the use of crossed polarisers, creating a virtually zero background. Secondly the problem with laser beam attenuation due to scattering in the smoke, especially with soot particles, decreases in importance with the fourth power of the laser wavelength. This means that infrared measurements represent a great advantage over measurements in the ultraviolet or visible wavelength range. It is concluded that IRPS shows great promise as a new diagnostics tool in fire technology for small-scale as well as for large scale experiments. Furthermore the in situ nature of the method should be emphasized since this means that valuable information is obtained that can not be extracted from sampling methods such as MS/GC or FTIR for example. This information is important, for example, in egress calculations and analysis of fire chemistry. The method can easily be adapted for other gases such as HF, NO, NO2, HBr, CO and SO2.

    Effect of gas cell pressure in FTIR analysis of fire effluents2014In: Fire and Materials, Vol. 39, no 7, p. 675-84Article in journal (Refereed)
    Abstract [en]

    The analysis of fire effluents using Fourier Transform Infrared Spectroscopy (FTIR) is increasing in the field of fire science. This technique is very powerful and may be very selective and precise if the FTIR instrument is properly calibrated. However, results are sensitive to instrumental parameters, including especially pressure effects on the contents in the measurement cell. This communication presents experimental and numerical evaluation of pressure effects in FTIR analysis, and an evaluation of the feasibility and limitation of pressure corrections. The work performed concerns experimental measurements on pressure influence with four different gases, at different levels of concentration, and for one of the gases with different equipment from two laboratories. Some of these results are compared with theoretical models obtained from HITRAN database. Finally, this communication proposes limitations to the range of validity of correction if the actual pressure and the pressure for calibration differ, and suggests a tolerance of ±10 Torr on pressure variation for application of the method.

    Flame Spread Modelling of Complex Textile Materials2011In: Fire Technology, Vol. 47, no 1, p. 85-106Article in journal (Refereed)
    Abstract [en]

    Flame spread in textile materials was modelled using two different simulation programs: the semi-empirical area-based code ConeTools, and the computational fluid dynamics, CFD, code Fire Dynamics Simulator, FDS, (version 5). Two textile products developed within the EU-project Flexifunbar were selected for study. The two products show a large difference in composition and application area, one material is developed to function as a protecting layer for the underlying structure in case of fire while the other is an insulating material with no requirements on fire performance. The products represent materials for which fire test results indicate a classification on either end of the rating scale for wall materials according to EN 13501. Two FDS-models were developed for the simulations. The first FDS model was a relatively simple model of the small scale Cone Calorimeter test (ISO 5660) which served the purpose of a first preliminary validation of the model for pyrolysis of the material. In the second FDS model, a model of the intermediate scale Single Burning Item, SBI, test method (EN 13823), the fire scenario was expanded to simulate flame spread over a surface. The work included determination of the necessary material properties. In ConeTools, the option to predict an SBI test was used. The results from the two simulation methods were compared to real SBI tests. Neither model was able to fully predict the heat release rate for these complex products. However, the results from both codes were accurate enough to correctly predict the fire rating class for wall linings according to EN13501.

    Design fire for a train compartment2009Report (Refereed)
    Abstract [en]

    The fire dynamics of a train compartment was investigated in detail. A full scale test was performed which showed that the compartment reached flashover three minutes after ignition. Small scale tests were performed on the wall and floor linings and on seat and table materials. The results from these tests were used as input to a CFD-model implemented in FDS5 (Fire Dynamics Simulator, v5). It was possible to obtain a good correlation between the FDS5 model and the full scale experiment. However, in order to obtain this correlation it was necessary to deviate significantly from the small scale experimental results regarding the thermal conductivity of the seat material. Further, the FDS5 model was highly sensitive to grid size. Despite these drawbacks it was concluded that FDS5 can be used to determine design fires for the tested compartment and for geometries and material selections which do not differ drastically from the tested configuration. A much simpler way to obtain a design fire is to use so called t2 pre-flashover fires. Using this approach it was found that the growth rate of the compartment fire was between fast and ultra fast, with characteristic time scales of 150 s and 75 s, respectively. Finally it was concluded that the main part of the heat release originated from the seats and that a reasonable good design fire can be found by studying the fire dynamics of individual seats only.

    Validation of CFD codes2008Conference paper (Other academic)
    Abstract [en]

    Use of CFD (computional fluid dynamics) software packages within fire performance based engineering and risk assessment is increasing substantially. An important part in the process is the quality assurance. For this reason the Swedish Rescue Services Agency (SRV) sponsored a unique research project. Within the project different codes for smoke spread and evacuation have been evaluated. This poster will focus on the evaluation of four CFD software codes.

    Image Quality Testing: Selection of Images for Assessing Test Subject Input2014In: Proceedings of the 8th International Conference on Sensing Technology, 2014, Vol. 7, p. 110-114p. 110-113, article id 5Conference paper (Other academic)
    Abstract [en]

    Determining image quality is dependent to some degree on human interpretation. Although entirely subjective methods of evaluating image quality may be adequate for consumer applications, they are not acceptable for security and safety applications where operator interpretation may lead to missing a threat or finding threats where they do not exist. Therefore, methods must be developed to ensure that the imagery used in security and safety applications are of sufficient quality to allow the operator to perform his job accurately and efficiently. NIST has developed a method to quantify the capability of imagers to provide images of sufficient quality to allow humans to perform specific perception-based tasks. A one-time human-perception based step is required that results in perception coefficients that are combined with lab-measured objective image quality indicators (IQIs) to calculate image quality. This work uses a d' evaluation method to examine the performance of test subjects in the human-perception based step, which was identification of a fire hazard in a set of grey-scale infrared images.

    Characteristics of lithium-ion batteries during fire tests2014In: Journal of Power Sources, ISSN 0378-7753, E-ISSN 1873-2755, Vol. 271, no Dec, p. 414-420Article in journal (Refereed)
    Abstract [en]

    Commercial lithium-ion battery cells are exposed to a controlled propane fire in order to evaluate heat release rate (HRR), emission of toxic gases as well as cell temperature and voltage under this type of abuse. The study includes six abuse tests on cells having lithium-iron phosphate (LFP) cathodes and, as a comparison, one test on conventional laptop battery packs with cobalt based cathode. The influence of different state of charge (SOC) is investigated and a limited study of the effect of water mist application is also performed. The total heat release (THR) per battery energy capacity are determined to be 28-75 kJ Wh-1 and the maximum HRR values to 110-490 W Wh -1. Hydrogen fluoride (HF) is found in the released gases for all tests but no traceable amounts of phosphorous oxyfluoride (POF3) or phosphorus pentafluoride (PF5) are detected. An extrapolation of expected HF emissions for a typical automotive 10 kWh battery pack exposed to fire gives a release of 400-1200 g HF. If released in a confined environment such emissions of HF may results in unacceptable exposure levels.
