摘　　要：建立了加油站油枪口加油过程的油气排放模型,对不同逸散速度、逸散方向、风速等条件下的油气排放进行了数值模拟,获取了加油过程的排放强度和影响范围。在加油站现场开展了加油过程排放实测,利用红外摄像机和PID检测仪记录了不同位置扩散浓度,通过对比模拟和实测数据,验证了模型的准确性。A model of oil and gas emission during the process of refueling was established,and the oil and gas emission was simulated under different conditions of escape velocity,escape direction and wind speed,and the emission intensity and influence range of refueling process were obtained.The emission measurement during the refueling process was carried out at the gas station site,and the diffusion concentration at different positions was recorded by infrared camera and PID detector.The accuracy of the model was verified by comparing the simulated and measured data.
