摘要

摘要: 管道裂纹泄漏率计算是破前漏（LBB）分析中的关键技术，采用与有效软件进行对比和与实验结果进行对比的方式，对国内自主研发的泄漏率计算软件PICLES进行验证研究。与已有成熟工程应用的国际同类软件（PICEP和SI-PICEP）对比，PICLES与其计算结果相差较小；与管道裂纹泄漏率实验结果对比，PICLES计算出的泄漏率与其相差−80.23%~−43.79%，PICLES计算的泄漏裂纹长度与实测裂纹长度相差21.84%~79.07%，说明将PICLES用于过冷水管道LBB分析具有较高的保守性。因此，PICLES可用于实际工程中的LBB分析。

Abstract: The calculation of pipe crack leakage rate is the key technology in leak-before-break (LBB) analysis. By comparing with the effective software and the experimental results, the domestic independently developed leakage rate calculation software PICLES is verified and studied. Compared with the international similar software (PICEP and SI-PICEP) with mature engineering applications, there is a small difference between PICLES and its calculation results. Compared with the experimental results of pipe crack leakage rate, the leakage rate calculated by PICLES is −80.23%~−43.79% different from that calculated by PICLES, and the leakage crack length calculated by PICLES is 21.84%~79.07% different from the measured crack length, which shows that the LBB analysis of supercooled water pipeline using PICLES is highly conservative. Therefore, PICLES can be used for LBB analysis in practical projects.
