有毒重气体连续泄露扩散模拟与风险评估
Dispersion modeling of hazardous weighty gas after continuous release and risk assessment
摘要
Abstract
Based on the computational fluid dynamics (CFD) of the weighty gas dispersion model and taking chlorine as release gas,this paper researches the characteristics of the movement and concentration distribution information for chlorine gas after continuous release in the case of different wind speed and different size of obstacles.Unity 3D software is applied to simulate diffusion process.The dividing damage levels for diffusion area are divided according to concentration distribution and variation characteristics,which is as the optimized scheme and technical support of evacuation and escape routes when the leaking accident happened.关键词
