ABSTRACT: In this paper is presented a simple possible model which can explain the thermal explosion problem, the existence of an induction period and a sudden rapid temperature rise. As state variables used for modeling are: the pressure, the temperature and the concentration. The time evolutions of these state parameters are analogically modeled using ordinary differential equations. The numerical simulations of the obtained model are made in Matlab/SimulinkTM. The validation of the model is realized by comparison between experimental data and simulation results, presenting a good accuracy.
Key words: thermal explosion, analogical modeling, numerical simulation, state Parameters
