摘要:
以伦敦中心城区示踪气体扩散试验为例,对城市建筑群中危险气体的迁移扩散以及周边人口暴露风险进行数值模拟分析.通过计算流体力学模型和暴露模型的耦合,模拟街区尺度近地面气云扩散过程,结合地理信息系统和建筑物数据库估算受影响的人口及其潜在的暴露水平,求解建筑物周围的时变质量浓度和暴露剂量分布.近地面的质量浓度时间序列表明,气云扩散受建筑物和道路布局影响显著;泄漏停止后部分建筑物背风向和狭窄街段内质量浓度稀释滞后,可能对人群健康构成潜在威胁.
Abstract:
An integrated approach incorporating computational fluid dynamics (CFD) model, exposure model, and geographic information system (GIS) is presented to predict the transfer and dispersion of dangerous gas, and estimate the exposed population in urban areas. A tracer gas experiment carried out in center London is simulated and analyzed. The results show that, given appropriate parameters, the CFD method coupled with a model of exposure is capable of predicting the time-varying concentrations and exposure levels around the complex arrangement of buildings, and the potentially affected population can also be roughly estimated using GIS and building database. The buildings and roads have important influence on the trajectory of the gas cloud near ground level. Significant amounts of cloud mass may stay longer in some building wakes or narrow street sections, which constitutes a threat to public health and safety.
