In this study, a fire test was performed for the railway vehicle seat in the Room Corner testfacility and two fire simulations for the fire test were carried out using two types of ComputationalFluid Dynamics model, and the results were compared. One set of Korean Saemaeul railroad car seatfor two persons was installed parallel to the sidewall of the room corner tester of the Korea RailroadResearch Institute, and a pan containing one liter of heptanes as an initial fire source was installed onthe central front end of the seat to conduct the test. To obtain the input factors for analyzing this test,cone-calorimeter tests and TGA(Thermo-Gravimetric Analysis) of every specimens of individualcomponents of the seat were conducted. Using FDS, the inside of the room, shape of the seat, andinitial fire source were modeled to be similar to the test conditions; fire analysis was conducted usingpyrolysis model. The analysis was conducted with the same shape and in the same domain as those ofFDS using FLUENT, a commercial CFD code. In this paper, the results of the analyses of FDS andFLUENT were compared with the test resu the differences between the two analysis codes wereexamined in analyzing fire growth using pyrolysis model.
