摘要
以30 000 m^(3)LPG低温常压罐为研究对象,利用FLUENT模拟液相泄漏蒸发扩散规律,研究了风速、温度、粗糙度、相对湿度等因素的影响及权重。结果表明:以上因素对扩散规律影响程度从大到小依次为风速、粗糙度、温度、相对湿度,其中风速是主控因素。研究结果可为事故预防和救援提供参考。
Taking 30 000 m^(3)LPG low-temperature atmospheric tank as the research object, the influence and weight of wind speed, temperature, roughness, relative humidity and other factors were studied by simulating the evaporation diffusion law of liquid phase leakage using FLUENT. The results showed that:the influence on the diffusion law was wind speed, roughness, temperature and relative humidity in descending order, among which wind speed was the main control factor. The research results could provide reference for accident prevention and rescue.
