摘要/Abstract

摘要： 由于我国北方地区冬季气温较低,成品油管道在输送过程中有时会发生冰堵现象。管道一旦发生冰堵,不但影响油品的输送,而且对生产造成不必要的损失,严重时还会造成安全隐患。基于FLUENT 数值仿真软件,研究了成品油管道中单个不同高度的冰堵段以及多个不同高度的冰堵段周围流场的变化。研究结果表明,随着冰堵高度的增加,单冰堵段前后压差呈非线性变化,多冰堵段前后压差同样呈非线性变化;单冰堵段前后流速变化相对平稳,而多冰堵段周围流速变化明显,流体分层效果较好,多冰堵段周围流体的速度分布规律与单冰堵段相似。

Abstract: The ice blocking could happen during the process of conveying products oil in the pipeline, because of the low temperature in north China in winter. The pipeline occurred ice blocking, not only oil transport was affected but also unnecessary damage of production was caused, and the potential safety hazard could exist when it became serious. Based on thenumerical simulation software FLUENT, the flow field distribution was calculated around the single and multiple ice blocks in products pipeline which were in different height. The research results showed that increasing with the height of the ice wall, the pressure difference of front and back produced nonlinear changes, the pressure distribution regularities of multiple ice also produced nonlinear changes. In the aspect of velocity, the velocity variation degree of front and back the ice block was relatively stable, but the velocity change process around the ice block was more obviously and layered effect was better, the speed distribution regularities of multiple ice blocks were similar to that of the single ice blocks.
