description | Modeling of methane-air mixture nonstationary combustion process in coal mines is performed. Analytical dependencies are formulated to perform modeling of methane-air mixture nonstationary combustion on the basis of FlowVision software complex. The adequacy of the computer model on the experimental data, given in the literature for 7 experiments, as well as on its own experimental data was verified. The average relative error of the model is from 10 to 20 %. The developed model is scaled for pipes with large diameters from 2 to 4 m and can be used to calculate non-stationary combustion for coal mine conditions. Modeling of nonstationary combustion for coal mine conditions was carried out. As a result, for the considered configurations of the mines it is established that: the maximum velocity of the flame front during detonation reaches 1400 m/s; the maximum temperature in the calculated region during detonation is 2440 °C; the maximum overpressure at detonation is 4 MPa; the calculated values of the radiation flux density at detonation reach 2200 kW / m2. |
