Abstract: Fire involves a number of chemical reactions, but most fire simulations do not consider multi-step chemical processes. Using multi-step chemical reactions enalbles more realistic fire simulation. In this study, ANSYS FLUENT® used to simulate pool fire with multi- step chemical reactions. It is possible to predict various species concentrations involved in the fire process, not only thermal properties. In this study, the fire is modeled using two different computational fluid dynamics software ANSYS FLUENT® and Fire Dynamic Simulator (FDS). The validity of the ANSYS FLUENT® fire simulation is assessed by comparing temperature and species concentration results with experimental and FDS results. Unlike FDS fire simulation, ANSYS FLUENT® fire simulation with multi-step chemical reactions is able to analyze intermediate species concentration compared with the experimental results. Furthermore, ANSYS FLUENT® fire simulation can measure various species involved in fire, so it is expected to predict various aspects of fire.
