WebbThis paper deals with a numerical simulation method, which enables the determination of transients caused by fires. The mathematical model, of the simulation method … WebbThe smoke temperature from simulations is slightly higher than that from experiments, especially near the fire source. Besides, as the distance becomes farther, the temperature difference between the simulations and experiments gradually tends to be zero. Overall, the reliability of simulation results in the branched roadway is verified. 3.
