Study on the Dispersion of Flammable and Toxic Gases

Ding Xinwei, Wang Shulan, Xu Guoqing (Department of Chemical Machinery, Dalian University of Science and Technology, Dalian 116012)  
Based on conservation of mass, energy and momentum of air dynamics, the numerical simulations of dangerous gases dispersion with new model has been made. For the purpose of verifying the math model, the simple dispersion wind tunnel was designed. Many stable release dispersion experiments of heavy and light gases (including carbon dioxide, propylene, acetylene, etc.) were conducted, the distribution of released gas was got. The influences of wind speed, discharge of disperse, density of gases were examined. The results of dispersion model were in good agreement with the results of dispersion experiments. The error between computing model and experiment was less than twenty percent, and the tendency of concentration was concordant, which proved the rationality of the math model. The software could provide suitable means for preventing the leakage of dangerous gases and remedying after leakage.
