Weerheijm, J. (author), van der Voort, M.M. (author), Verreault, J. (author), van den Berg, A.C. (author)Tunnel accidents with transports of combustible liquefied gases may lead to explosions. Depending on the substance involved this can be a Boiling Liquid Expanding Vapour Explosion (BLEVE), a Gas Expansion Explosion (GEE) or a gas explosion. Quantification of the risk of these scenarios is important to take informed decisions on tunnel design and...conference paper 2015

Weerheijm, J. (author), van den Berg, A.C. (author)Tunnel accidents with transports of dangerous goods may lead to explosions. Risk assessment for these accidents is complicated because of the low probability and the unknown, but disastrous effects expected. Especially the lack of knowledge on the strength of the explosion and the consequences for the tunnel user, the tunnel lining and the...conference paper 2014

(author)The need for transportation and storage of CO2 in bulk quantities is likely to increase in the near future. The handling of CO2 on such scale gives rise to a number of technological challenges and safety aspects. The accidental rupture of a vessel containing liquefied CO2 may lead to a Boiling Liquid Expanding Vapour Explosion (BLEVE). Whether...article 2013

van der Voort, M.M. (author), van den Berg, A.C. (author), Roekaerts, D.J.E.M. (author), Xie, M. (author), de Bruijn, P.C.J. (author)Explosive evaporation of a superheated liquid is a relevant hazard in the process industry. A vessel rupture during storage, transport or handling may lead to devastating blast effects. In order to assess the risk associated with this hazard or to design protective measures, an accurate prediction model for the blast generated after vessel...article 2012

(author)Shock tube experiments and simulations are conducted with a spherical gelatin filled skull- brain surrogate, in order to study the mechanisms leading to blast induced mild traumatic brain injury. A shock tube including sensor system is optimized to simulate realistic impro-vised explosive device blast profiles obtained from full scale field...article 2011

(author)The use of space is being intensified near and above transport routes of hazardous materials. In The Netherlands, some buildings are even realized above infrastructure with transport of hazardous materials like LPG. An accident with an LPG-tank may result in a BLEVE, causing injuries and large structural damage to the spanning building and the...conference paper 2010

van den Berg, A.C. (author), TNO Defensie en Veiligheid (author)The availability of powerful computers these days increasingly enables the use of CFD for the numerical simulation of explosion phenomena. The BLAST software consists of a compilation of codes for the numerical simulation of the gas dynamics of explosions. Each individual code has been tailored to a specific application. After a brief...article 2009

(author), TNO Defensie en Veiligheid (author)A quantitative risk assessment (QRA) tool has been developed by TNO for the external safety of industrial plants with a dust explosion hazard. As a first step an industrial plant is divided into groups of modules, defined by their size, shape, and constructional properties. Then the relevant explosion scenarios are determined, together with...article 2007

(author)This report presents a new method to calculate the blast effects originating from an exploding vessel of liquefied gas. Adequate blast calculation requires full knowledge of the blast source characteristics, that is, the release and subsequent evaporation rate of the flashing liquid. Because the conditions that allow explosive evaporation are...article 2006

(author), TNO Preventie en Gezondheid (author)Objective: Endovascular aneurysm repair is an alternative treatment of abdominal aortic aneurysm. The procedure is less invasive, and morbidity and most probably mortality are reduced. However, some problems, such as endoleakage, are yet to be resolved. Endoleakage can occur after graft migration, as a result of insufficient fixation of the...article 2004

(author), Gaubius Instituut TNO (author)Objective: One of the most life-threatening vascular diseases is rupture of an abdominal aneurysm. The conventional treatment is based on surgical reconstruction. An alternative treatment is endovascular aneurysm repair (EVAR). Despite many advantages, one of the problems of EVAR is endoleakage from deficient healing between the aortic neck and...article 2002
