  • Analysis of methodologies and uncertainties in the prediction of BLEVE blast 

    Hemmatian, Behrouz; Planas Cuchi, Eulàlia; Casal Fàbrega, Joaquim (2014)
    Article
    Open Access
    Even though BLEVEs have been studied by a number of authors, there are still significant gaps in their knowledge and in the prediction of their physical effects. Diverse methodologies have been proposed to calculate ...
  • 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 ...
  • BLEVE: The case of water and a historical survey 

    Hemmatian, Behrouz; Casal Fàbrega, Joaquim; Planas Cuchi, Eulàlia; Rashtchian, Davood (2019-01-01)
    Article
    Restricted access - publisher's policy
    After a short update of the current more accepted definition of BLEVE, the special features of water BLEVEs are analyzed. The stronger overpressure wave generated in the case of water as compared to that of other substances ...
  • Comparative analysis of BLEVE mechanical energy and overpressure modelling 

    Hemmatian, Behrouz; Planas Cuchi, Eulàlia; Casal Fàbrega, Joaquim (2017-02-01)
    Article
    Open Access
    The mechanical effects of a BLEVE are overpressure and ejection of fragments. Although fragments reach much longer distances, peak overpressure can be very strong over a certain area. Diverse authors have proposed methodologies ...
  • Contribution to the study of boiling liquid expanding vapor explosions and their mechanical effects 

    Hemmatian, Behrouz (Universitat Politècnica de Catalunya, 2016-07-18)
    Doctoral thesis
    Open Access
    Boiling Liquid Expanding Vapor Explosions keep occurring from time to time in process plants, storage areas and transportation by road or rail, often with severe effects. There is no doubt that a better knowledge of their ...
  • Essential points in the emergency management in transport accidents which can lead to a bleve-fireball 

    Hemmatian, Behrouz; Casal Fàbrega, Joaquim; Planas Cuchi, Eulàlia (2017)
    Article
    Restricted access - publisher's policy
    Huge amounts of hazardous materials are transported by rail and road, being from time to time involved in traffic accidents. In these cases, flammable materials such as, for example, LPG, can originate a severe accident ...
  • Fire as a primary event of accident domino sequences: The case of BLEVE 

    Hemmatian, Behrouz; Planas Cuchi, Eulàlia; Casal Fàbrega, Joaquim (2015-07-01)
    Article
    Open Access
    The domino sequences found in major accidents have been analyzed for a large set of cases (330); the first event triggering the domino effect was an explosion or a fire, both with approximately the same contribution; the ...
  • The significance of domino effect in chemical accidents 

    Hemmatian, Behrouz; Abdolhamidzadeh, B; Darbra Roman, Rosa Maria; Casal Fàbrega, Joaquim (2014)
    Article
    Restricted access - publisher's policy
    A historical survey was performed on 330 accidents involving domino effect, occurred in process/storage plants and in the transportation of hazardous materials; only accidents occurred after 1st-January-1961 have been ...
