On the Models of Calculating Severe Hazard Caused by Gas-leaking

摘要

In recent years, the frequent occurrence of gas leaking of delivery pipes has posed greatrnthreat to the delivery operation, and brought about great loss of national economy andrnpeople's lives and property. By using Pasquil-Gifford model, based on the intrinsicrnfeatures of natural gas, this paper analyzes the forms in which gas leaking may occur.rnModels are built to calculate the degree of gas leaking occurred on different conditions,rnthe diameter of flame, and the radium of explosion so as to estimate the range andrndegree of the gas-leaking, and to minimize the damage to human beings andrnenvironment. Finally, according to the models, the consequences caused by gas-leakingrncan be well studied and evaluated.
