Simulation of detonation and blast waves propagation

摘要

Among the priorities of the Slovak Republic we consider the protection of elements of critical infrastructure, indispensably including the transport infrastructure, which has to be constantly improve and modernize. Researching the protection of these elements, part of the researchers is focusing on ways to protect assets from the blast effects. An explosion can’t be solely caused due to a terrorist attack or other violent crime. Most frequent causes include electrical short circuits, gas pipeline disturbances, or vehicle crashes, which can cause transportation collapse for up to a few days. Before realization of the blast protection of assets, a number of simulations are required to provide the necessary information for application of a suitable way how to secure a selected critical infrastructure element. The most important issue is to know the blast waves propagation and their mitigation. The paper is focused on the various simulation methods to simulate the blast wave propagation as pressure-time function, compressed balloon, mapping algorithm or solid TNT.
