Abstract

In this paper, the large eddy simulation was used and the one-equation method was adopted as the sub-grid method. In addition, the simulations are performed in three-dimensional, unsteady, and single-phase case and the Froude number is considered 0.000255. To investigate the effect of the combustion model, the combustion model of flamelet generated manifold is used in the simulation of fire in the room and the results of this combustion model are compared with infinite fast chemistry models and eddy dissipation models. Comparing the results, it can be seen that in the fire scenario in the room with a heat release rate of 62.9 kW, the mean temperature in the flame is approximately 1500 Kelvin. Also, the results of the eddy dissipation combustion model and infinite fast chemistry predict the temperature results better than the flamelet generated manifold combustion model; but, all three combustion models are close to experimental results with a relative error of less than 10%, in predicting the velocity. Due to the low computational cost of the flamelet generated manifold model and the ability to use detailed kinetics in this combustion model, as well as its acceptable accuracy, it is appropriate to use this model in the compartment fire simulation.
