摘要
对于气体泄漏的几种释放量进行了模型试验,数值模拟了在带有燃气管道的共同沟中燃气泄漏后的摩尔组分浓度分布.对比模型试验结果发现:在气体泄漏点的一定范围内,标准κ-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,工程中的三维湍流问题可以进行数值仿真.
The tests on several rates of flow of gas were carried out.Based on the tests,distribution of gas mole fraction in utility tunnel was calculated using numerial simulation.In comparison with the experimental results,it is found that the gas mole fraction can be simulated by standard κ-ε turbulent model and the numerical accuracy nearby gas leakage point is almost good according to the demand of engineering.The results show that three-dimensional tuberlence in engineering can be simulated.
