安全评价中的气体扩散模型及应用

Gas Diffusion Model and Its Application in Safety Assessment

安全评价中如何预测和模拟气体储罐在完全破裂后介质瞬间泄漏的动态扩散过程目前还没有合适的模型,通常只能借用环保领域中的高斯模型和Sutton模型,但环保领域的模型为稳态扩散模型,不含时间变量,并不适合动态扩散过程。提出了安全评价专用的气体扩散模型,并应用于实际评价。

Tbere still isn＇t suitable model to forecast and model dynamic diffusion process of leakage in safety assessment when gas container explodes and usually Gauss model and Sutton model in environmental protection field are used, but these two kinds of models belong to static diffusion model, containing no time variable and not suitable for dynamic diffusion process, so special gas diffusion model used in safety assessment is established and the actual application is also discussed.
