摘　　要：为了提高液体管道泄漏声波检测的精度,结合液体泄漏处空泡产生和发展的机理,采用fluent软件对液体管道泄漏的流场进行数值模拟分析。分析结果表明:管道液体压力越大,声波强度越大;管道泄漏孔径越大,声波强度越大。分析结论对液体管道泄漏声波检测具有重大指导意义。The paper apply Fluent to analyze the flow simulation of leakage for enhancing the accuracy of the detection. The producing and developing of a Cavity are elaborated, and the affecting of pressure in the water pipelines and the size of pore are showed. The results have important sense for the detection of leakage and industrial applications.
