2) bent pipe
弯曲管道
1.
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。
