The temperature inside the burning car and the mass loss rate were measured. The cars were ignited either at the splashguard of the right rear wheel or at the left front seat in the passenger compartment with a gasoline spill. As the glass breakage is one of the most important factors affecting the course of an automobile fire, a simple practical criterion to determine when window breakage will occur is proposed.įour full-scale fire experiments using 4-door sedan passenger cars were carried out. Due to high computational requirements, a parallel version of the calculation is studied, and the influence of parallelization on performance and accuracy is tested as well. A parameter study related to some selected material properties, which shows that seat material properties are the most important for the fire development, is described. The comparison confirms the accuracy of the simulation. The results of simulations are compared with the results of the measurements obtained during a full-scale fire experiment conducted in Povazsky Chlmec (Slovakia) in 2009. In this article, computer simulations of fire in an automobile interior and its influence on an adjacent vehicle are investigated. Knowledge of the course of an automobile fire is an important issue in automobile fire safety and can have a significant impact on fire safety measures in car parks and other structures with a high concentration of automobiles. During the research, it was found that although the application of Pyrosim software has certain limitations in the simulation of automobile fire simulation, the research results can still provide a reference for automobile fire simulation and automobile fire prevention and control. According to the simulation results, the flue gas simulation analysis and thermal power analysis were done, and the simulation results were analyzed and discussed in depth. Through research, it is found that the fire of a bus has its own characteristics, which can be divided into four stages: initiation, flashback, deflagration, and stability. In this study, Auto CAD was used to establish a three-dimensional bus model, and then it was imported into Pyrosim software, and Pyrosim software was used to simulate the fire of the bus model.
Aiming at the problem of automobile fire simulation, a common model bus is taken as the research object, and the Pyrosim software is used as a tool to realize the fire simulation.
