城燃管道街道峡谷泄漏扩散CFD数值模拟
CFD Modeling of the Releases and Dispersion of Accidental City Gas Pipeline in Urban Street Canyons
摘要
Abstract
City gas pipelines are always under the threat of municipal construction. Unlike in the wild, the building of the city will cause lots of trouble to the dispersion of the gas released, and the lives and property safety of people may be threatened. The dispersion of the city gas released in the street canyons was analyzed based on the two ~ dimensional CFD model. The situation before and after the shutting down of the block valves were studied respectively. The numerical simulation results show that the wind plays a leading role on the dispersion,and the aspect of the street canyon has significant effects on inner vortex airflow fields which will make the gas difficult to disperse.关键词
