圆锥管 meaning in Chinese
conical tube
Examples
- Taper pipe threads with 60 degree
圆锥管螺纹 - 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。
