Simulation And Anysis Of Release And Dispersion For Hazardous Gases Transportation

With the development of the chemical industry, there are more kinds of hazardous materials being produced, stored and used, and they are carried out in a large amount. Because of the transportation, there are more and more accident happened. In order to prevent and control the mischief caused by the dispersion accident, integrating the method of risk analysis, through analyzing the dispersion pattern of hazardous materials to choose a suitable route has been an important problem.On-based of this, the thesis did some research below:First, based on the summary of relative reference, we retrospected domestic and foreign researchers on the hazardous materials transportation and the spread of harmful gases leaking Research. Then explore on the basis of a thesis discussed the hazards, risk analysis and evaluation of the relevant basic analysis and the transport of hazardous goods.Chapter 3 under the summarizing of common gas leak in diffusion model, discussed the preparatory work for simulation and analysis and using Aloha and Matlab for the simulation of the gas diffusion. Simulation in two ways, a variety of factors influence the spread of a gas leak, and integration risk, analysis of the differences in the risk factors under the conditions of the population.Chapter 4, Under the simulating area and Gaussian model, based on the harmful consequences of the probability function leak, Integrated of different transport routes for the actual situation, through Risk analysis pointed the method of optimal routing selection for transportation, and improved risk analysis of hazardous substances, also for the transport of hazardous materials and how to minimize the risks to the population from the process of choosing a route basis.Chapter 5 according to the simulation results analyzed the hedging behavior under the conditions of the population in different factors, and this provided a practical measure to reduce the population of casualties.
