Abstract

Abstract

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.
- fire simulation,
- velocity attenuation,
- smoke rollback,
- length-diameter ratio,
- heat release rate,
- mine fire
