Numerical Reconstruction of a Deflagration Accident in a Factory Plant

An explosion fire occurred in a factory plant which three people are killed. A preliminary site survey concluded that a certain concentration of n-Heptane ignited by electrical work and then deflagration happened. To verify the survey conclusions the numerical reconstruction method is used, and the evaporation and distribution of n-Heptane in plant is calculated. The simulation results show that the concentration of n-Heptane is in the range of explosive limit which instructs the numerical reconstruction can give a technical support for disaster investigation.
