The main causes of severe industrial accidents are fire, explosion and releases of toxic materials. Among these causes, explosion hazards are getting more attention these days due to ever-increasing use of gases as energy and raw material. The use of advanced explosion simulation packages are increasing domestically as well as internationally, even though their predicting accuracies are not sufficient to our expectations. In this research, enhanced modeling and simulation methodologies for accidental explosion and consequence analysis were investigated by comparing the advantages and disadvantages of various available approaches such as experimental, phenomenological and computational fluid dynamics models and simulation systems, including quantitative analysis of the explosion overpressure results. Recent advances in computing, network and visualization technologies and their contributions to explosion research and simulations are also discussed. A Computational Grid-based, simulation environment is suggested as a practical way to improve the prediction accuracy and the exploitable problem size of explosion simulations by using state-of-the-art large-scale, massive computations. |
