2. In this paper , an automotive catalytic converter with honeycomb substrate has been studied and it ' s found that catalytic converter efficiency cannot be given full play . to resolve this problem , a kind of design method that a deflector is put in the diffuser to farther improve catalytic converter efficiency is put forward , and the research on this method is carried out
   本论文针对目前车用蜂窝载体式催化转化器进行了转化效率的研究，指出常规结构催化转化器存在转化效率没有充分发挥的问题，并提出了一种进一步提高其转化效率的设计方法：在扩张管处加一个弥散器装置。
3. A mathematical model of flows in the substrate was established using the equivalent continuum approach , and multi - dimensional numerical simulation of the steady flows in the catalytic converters was performed . simulation results show that the separation and vortex , which cause the pressure loss and the velocity non - uniformity at the front of the first substrate , are generated near the wall of the conical pipe . in addition , the larger the inlet cones angle the more the pressure loss and maldistribution in converters , however , when the angle enlarges enough the pressure loss would be decrease
   结果显示气流在扩张圆锥管壁附近出现分离产生较强的扰动，造成局部流动损失和载体前气流速度沿径向分布不均匀；入口扩张管结构对催化器的流动特性有很大影响，但并非扩张角越大，催化器流速武汉理工大学硕士学位论文分布的不均匀性和压力损失也增大，而是存在着一个最佳角度，但当扩张角增大到一定程度以后，扩张角对流速分布和压力损失的影响变小。
