A new procedure to estimate BLEVE overpressure
Hemmatian, Behrouz; Casal Fàbrega, Joaquim; Planas Cuchi, Eulàlia (2017-10-01)
Article
Accés obertSeveral 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 ... -
Analysis of methodologies and uncertainties in the prediction of BLEVE blast
Hemmatian, Behrouz; Planas Cuchi, Eulàlia; Casal Fàbrega, Joaquim (2014)
Article
Accés obertEven 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 ... -
BLEVE: The case of water and a historical survey
Hemmatian, Behrouz; Casal Fàbrega, Joaquim; Planas Cuchi, Eulàlia; Rashtchian, Davood (2019-01-01)
Article
Accés obertAfter 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
Accés obertThe 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)
Tesi
Accés obertBoiling 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
Accés restringit per política de l'editorialHuge 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
Accés obertThe 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 ... -
Prediction of BLEVE mechanical energy by implementation of artificial neural network
Hemmatian, Behrouz; Casal Fàbrega, Joaquim; Planas Cuchi, Eulàlia; Hemmatian, Behnam; Rashtchian, Davood (2020-01-01)
Article
Accés obertIn the event of a BLEVE, the overpressure wave can cause important effects over a certain area. Several thermodynamic assumptions have been proposed as the basis for developing methodologies to predict both the mechanical ... -
The significance of domino effect in chemical accidents
Hemmatian, Behrouz; Abdolhamidzadeh, B; Darbra Roman, Rosa Maria; Casal Fàbrega, Joaquim (2014)
Article
Accés restringit per política de l'editorialA 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 ...
