摘要:Different air inlet volumes into belt roadway of ascensional ventilation seriously affect airflow stability during fire, and improper disposal will lead to deterioration of disaster. According to airflow stability analysis, and based on control equations of flow and SIMPLE algorithm, the fire parameters in disaster period were solved, and the airflow state in belt roadway under different air inlet quantities was also clear. The simulation results showed that steady air inlet was helpful to maintain airflow stability and prevent the disaster spreading to broader area. The simulation can guide disaster control and avoiding of ascensional ventilation belt roadway during fire.
