Multidimensional Mixed Simulation Study on Smoke Propagation Features of Mine Fire

Using multiscale modeling technique to simulate the mine fire has the features of short time-consuming and high precision. The simulating results indicated that one-dimensional modeling could overestimate the temperature of fire. Multiscale modeling is more sensitive than one-dimensional modeling in variation of airflow parameter, which can give a more rapid response to the change of temperature or air velocity. Thus the simulation results are more accurate.
