A new procedure to estimate BLEVE overpressure
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 Boiling Liquid Expanding Vapour Explosion (BLEVE) and the associated overpressure. A new method, simple and easy to use, is presented which only requires the vessel filling de...
متن کاملComparative Analysis of Bleve Mechanical Energy and Overpressure Modelling
A 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 for the estimation of the explosion energy and peak overpressure from these type of explosions, based on different thermodynamic and physical assumptions. Here these metho...
متن کاملEffects of blast overpressure on the ear: case reports.
The case histories of five patients who experienced blast overpressure in excess of 200-dB peak pressure level are presented. Despite the significance of the sound pressure levels received in a military training accident and the severe injuries that resulted from the blast, these individuals experienced substantial improvement of hearing 1 year later. Undoubtedly, successful surgical interventi...

متن کاملModeling and Simulation of Blast Wave for Pressure Sensor Design
In this paper a universal model for pressure waves generated by high energy charge explosives and gunshots is developed for determining the pressure vs. time profile (P-T curve) at a given point in space which is useful for design and characterization of pressure micro sensors and explosives etc. The simulation of the model is carried out through virtual instrumentation (VI) using LabVIEW. The ...
