    Article
    Open Access
    The ClimaDat station at Gredos (GIC3) has been continuously measuring atmospheric (dry air) mixing ratios of carbon dioxide (CO2) and methane (CH4), as well as meteorological parameters, since November 2012. In this study ...
  • Interpolation framework to speed up near-surface wind simulations for data-driven wildfire applications 

    Rios, Oriol; Jahn, Wolfram; Pastor Ferrer, Elsa; Valero Pérez, Mario Miguel; Planas Cuchi, Eulàlia (2018-04-23)
    Article
    Open Access
    Local wind fields that account for topographic interaction are a key element for any wildfire spread simulator. Currently available tools to generate near-surface winds with acceptable accuracy do not meet the tight time ...
  • Prediction of lift-off distance in choked and subsonic hydrogen jet fires 

    Bradley, Dereck; Casal Fàbrega, Joaquim; Palacios, Adriana (2017-11-23)
    Article
    Open Access
    Hydrogen jet flames, as a consequence of their greater reactivity, have a number of characteristics that are different from other flames. These are reviewed, as are the various attempts that have been made to characterise, ...
  • Temporal and spatial variability of ground level atmospheric methane concentrations in the Ebro River Delta 

    Agueda Costafreda, Alba; Grossi, Claudia; Pastor Ferrer, Elsa; Rioja, Eva (2017-07)
    Article

    Deltas provide many worthy ecosystem services. Yet, delta basins are quite vulnerable, especially in the face of climate change, which can affect the outcome of both agriculture and biodiversity. Moreover, rice paddy ...
  • Configuration factors for ground level fireballs with shadowing 

    Vílchez, Juan Antonio; Muñoz, Miguel; Bonilla, Juan M.; Planas Cuchi, Eulàlia (2018-01-01)
    Article
    Open Access
    This paper presents new configuration factors for a fireball located at ground level, as radiation emitting source, and a differential receiver, considering the shadow effect of a third finite area that stands between them. ...
  • A new method for performing smouldering combustion field experiments in peatlands and rich-organic soils 

    Pastor Ferrer, Elsa; Oliveras Menor, Immaculada; Urquiaga-Flores, Erickson; Quintano Loayza, Jose Antonio; Manta Nolasco, Maria Isabel; Planas Cuchi, Eulàlia (2017-12-08)
    Article
    Open Access
    Smouldering ground fires have severe environmental implications. Their main effects are the release of large amounts of carbon to the atmosphere with loses of organic soil and its biota. Quantitative data on the behaviour ...
  • Pyrolysis gases released during the thermal degradation of insulation materials based on straw fibers 

    Chetehouna, Khaled; Belayachi, Naïma; Lemée, Laurent; Hoxha, Dashnor; Rengel Darnaculleta, Francisco de Borja (Springer, 2015-07-16)
    Article
    Open Access
    Interest in recovering and valorizing agricultural biomass residues has increased in recent years in response to emerging economic opportunities and the potential for more sustainable use of renewable and easy available ...
  • Investigation on the thermal degradation and kinetic parameters of innovative insulation materials using TGA-MS 

    Chetehouna, Khaled; Belayachi, Naïma; Rengel Darnaculleta, Francisco de Borja; Hoxha, Dashnor; Gillard, Philippe (2015-04-13)
    Article
    Open Access
    Thermogravimetric analyzer coupled to a mass spectrometer (TGA-MS) was used to study the thermochemical behavior of eight samples. Two varieties of straw (wheat and barley) and two others of binder (lime and plaster) have ...
  • Computational analysis of fire dynamics inside a wind turbine 

    Rengel Darnaculleta, Francisco de Borja; Pastor Ferrer, Elsa; Hermida, Debora; Gómez, Eugenio; Molinelli, Luis; Planas Cuchi, Eulàlia (2017-06-15)
    Article

    Wind turbines are generally considered cost-effective, reliable and sustainable energy sources. Fires are not common in wind turbines, but a significant number of fires occur every year due to the large number of turbines ...
  • A new procedure to estimate BLEVE overpressure 

    Hemmatian, Behrouz; Casal Fàbrega, Joaquim; Planas Cuchi, Eulàlia (2017-10-01)
    Article
    Open Access
    Several methodologies, based on different thermodynamic assumptions and requiring substance properties and thermodynamic data, have been proposed in the literature for the prediction of the mechanical energy released by a ...
  • Introduction of the human factor in the estimation of accident frequencies through fuzzy logic 

    González Dan, J.R.; Arnaldos Viger, Josep; Darbra Roman, Rosa Maria (2015-09-14)
    Article
    Restricted access - publisher's policy
    The frequency of occurrence of an accident scenario is one of the key aspects to take into consideration in the field of risk assessment. This frequency is commonly assessed by a generic failure frequency approach. Although ...
  • Monte carlo simulation as a tool to show the influence of the human factor into the quantitative risk assessment 

    González Dan, José Roberto; Guix Pujolar, Alan; Martí Gregorio, Vicenç; Arnaldos Viger, Josep; Darbra Roman, Rosa Maria (2016-07)
    Article
    Open Access
    The frequency of occurrence of an accident is a key aspect in the risk assessment field. Vari- ables such as the human factor (HF), which is a major cause of undesired events in process industries, are usually not considered ...
