为分析评价压水堆核电厂稳压器波动管的布置方式对热分层现象的影响,提出增加准水平段的倾角和在与主管道相连处增加一段竖直管段2种方案共6种布置方式。利用计算流体力学(CFD)分析方法,对采取不同布置方式的波动管的热分层现象进行数值模拟,得到每种布置方式的波动管在不同波动流速下的准水平段管道截面最大温差分布。对比分析结果表明:增大波动管准水平段的倾角可以减弱热分层现象,但无法彻底消除该现象;在波动管与主管道相连的接管嘴处增加一段竖直管段能够有效减弱并消除热分层现象。

Background The perioperative aortic dissection （AD） rupture is a severe event after endovascular stent graft placement for treatment of type B AD. However, this life-threatening complication has not undergone systematic investigation. The aim of the study is to discuss the reasons clAD rupture after the procedure. Methods The medical record data of 563 Stanford type B AD patients who received thoracic endovascular repair from 2004 to December 2011 at our institution were collected and analyzed. Double entry and consistency checking were performed with Epidata software. Results Twelve patients died during the perioperation after thoracic endovascular repair, with an incidence of 2.1%, 66.6% were caused by aortic rupture and half of the aortic rupture deaths were caused by retrograde type A AD. In our study, 74% of the non-rupture surviving patients had the free-flow bare spring proximal stent implanted, compared with 100% of the aortic rupture patients （74% vs. 100%, P=-0.213）. The aortic rupture patients are more likely to have ascending aortic diameters 〉4 cm （62.5% vs. 9.0%, P=0.032）, involvement the aortic arch concavity （62% vs. 27%, P=-0.041） and have had multiple stents placed （P=0.039）. Conclusions Thoracic AD endovascular repair is a safe and effective treatment option for AD with relative low in-hospital mortality. AD rupture may be more common in arch stent-graft patients with an ascending aortic diameter 〉4 cm and with severe dissection that needs multi-stent placement. Attention should be paid to a proximal bare spring stent that has a higher probability of inducing an AD rupture. Post balloon dilation should be performed with serious caution, particularly for the migration during dilation.
