基于ALOHA软件快速模拟液氨泄漏警戒范围

摘要

通过ALOHA软件模拟不同环境下液氨泄漏的警戒范围,分析云层、湿度、温度、风速对警戒范围的影响.结果表明,无云和少云天气下警戒范围比多云天气下的大得多;湿度对警戒范围无影响;警戒范围随温度升高有小幅度扩大;风速越大,警戒范围越小.%The liquid ammonia leaking accident's influence regions in different situations were decided through the ALOHA software, and the effects of clouds, humidity, temperature and wind speed to the influence regions were analyzed.Results showed that, the area is bigger when there is no or little clouds; the humidity doesn't affect the area; the area enlarge a little with the increase of temperature; and the higher the wind speed is, the smaller the area is.
