Abstract
Vapor Cloud Explosion (VCE) is one of the main industry accidents. Many models have been developed to predict accident consequences. And the weight of vapor in the cloud before cloud is ignited is a very important parameter for these models. In this paper, numerical simulation on the weight of vapor in the cloud caused by evaporation of flammable and volatile liquid released is done. Firstly, pool dynamic spreading and evaporation processes are analyzed in details. Secondly, the shortcomings of current models describing these processes are pointed out. Conservation of mass is used to connect spreading model and evaporation model. And factors that have effects on total quantity of vapor in cloud, such as minimum pool depth, release mode and geography condition around (dike exists or not), are also considered. In order to solve the differential equations, finite difference and Newton iterance are used. Thirdly, simulation on the weight of vapor in the cloud caused by evaporation of benzene released is given. At last, research emphases in this field in future are pointed out.
