| Abstract: | In order to improve the localization accuracy and efficiency of leakage in hot oil transportation pipeline,the localization algorism based on the change velocity of negative pressure wave along pipeline was analyzed.The proper leakage localization domain was derived by using the inequality.The numerical algorism for leakage point localization was improved.According to the approximate linear relation of velocity of the negative pressure wave with pipeline transportation temperature and the temperature change of crude oil along the pipeline,an analytical expression of mathematical model for leakage point localization in hot oil transportation pipe line was put forward.This expression can improve the efficiency of localization algorithm and real-time ability of detection system for pipeline leakage. |
