curved duct是什么意思

网络释义

用法例句

The Taylor-Dean flow through a curved duct of square cross section,in which walls of the duct except the outer wall rotate around the center of curvature and an azimuthal pressure gradient is imposed,is investigated numerically using the spectral method.

流过横截面为正方形的弯曲管内的泰勒-迪安流,除了外墙以外的其它墙壁随着弯曲管中心轴旋转,沿着管的轴向具有压力梯度。

Using finite element method,the FSI vibration characteristic of the bent pipe system and the flow characteristics of fluid within the bent pipe system are calculated and analyzed.

由于管道的弹性作用,管道壁面又会反过来影响管内流体流动情况,两者之间存在复杂的耦合作用;弯管内侧壁附近能量损失较大,静压分布从0~°90°截面始终是外侧高于内侧,进口段湍动能较小、拐弯处较大,管道内流体流速在弯曲管道转角处相对较高。

As an example, the results of 3-D turbulent incompressible flow in 90° curved duct with strong curvature are presented.

作为算例，本文给出了三维９０°强曲率弯曲管道中气流的不可压缩紊流状态的数值计算结果，并与相关的实验数据进行了对比，结果是满意的。
