ADVANCES IN MODELLING THE RISKS ASSOCIATED WITH GAS EXPLOSIONS IN CONFINED SPACES
Abstract
Process and plant design need to be continuously improved, the use of new safety concepts to a full extent being one of the key parameters leading to their sustainable improvement. Accidents occurred over time in industrial facilities where explosive gas or vapor atmospheres may be present have put the explosion risks high on the agenda of regulators, operators, accident investigators or researchers in the field. Accidental flammable gas leaks in mixture with air may generate explosive atmospheres which once ignited lead to explosion type events resulting in large overpressures causing significant damages to process installations or even fatalities. Harmful effects converted into fatality rates, referred to as vulnerability modeling is of significant importance for process quantitative risks assessment. The paper deals with data and research which lay ground for computational modelling for assessing the hazardous area extent and risks associated with gas leak explosions, taking into account computational investigations on the behavior of accidental flammable gas releases and on the effects of the generated explosive atmosphere?s explosion in confined spaces.
