DETERMINATION OF THE CONSEQUENCES OF POSSIBLE INDUSTRIAL ACCIDENTS

摘要

The paper is devoted to calculations of the consequences relating to accidental vapour cloud explosions. For this purpose, a general methodology has been developed and applied. The methodology consists of two steps: the first one deals with blast wave characterization - Multi-Energy method has been used, the second one deals with the propagation of the generated blast wave in surrounding air and wave-building interaction - the LS-DYNA code has been applied. The methodology has been applied to a case of unconfined non-obstructed hydrogen cloud explosion in site. An example of the application is presented in the paper. The methodology presented can be used both to determine the consequences of an accidental vapour cloud explosions for risk analysis purpose and at the same time also as an optimalization design tool which enables to minimize consequences of possible explosions taking into account various plant layouts.
