摘要:
在模型试验的基础上,数值模拟了在带有燃气管道的共同沟中燃气泄漏后的浓度分布.对比模型试验结果发现,在气体泄漏点的一定范围内,标准k-ε湍流计算模型能够模拟燃气的泄漏,数值计算的燃气浓度能够满足工程精度要求.
Abstract:
The distribution of inflammable gas mole fractions in utility tunnels was presented,via numerical simulation. Experiment results show the behavior of the gas mole fraction can be simulated by a standard k-ε turbulent model. The accuracy of this method is satisfactory for engineering purposes within a limiting distance from the point of gas leakage.
