摘　　要：以卧式储罐为例,研究了变截面储罐孔洞泄漏源模型及其数值计算方法。基于牛顿-科茨公式和辛普生积分法,采用复合求积的数值计算方法和VB软件编程技术,可计算任意泄漏时间t和泄漏高度h时的泄漏速率u和泄漏量Qm等参数。基于算例卧式轻油储罐的连续泄漏事件,运用statistical软件,绘制了h-t、Qm-t以及Qm-h关系曲线。研究成果不仅解决了传统小孔泄漏计算的局限性,而且为研究不规则储罐的泄漏过程提供了新的方法。Taking the horizontal tank as an example,hole leakage resource model and its numerical method for variable cross section tanks are studied. Based on Newton-Cotes formula and Simpson rule,parameters like random leakage time t and leakage rate u at leakage height h as well as leakage volume Qm can be calculated by adopting compound integrated numerical method and VB software programming technique. On the basis of a continuous leakage case occurred in a horizontal tank,relation curves such as h-t. Qm-t and Qm-hare plotted using statistical software. It is considered that the study result not only breaks through limitations in conventional method to compute small hole leakage,but also provides a new method to study irregular leakage course of the tanks.
