4)  curved pipe surface
曲管面
5)  curved pipes conveying fluid
输液曲管
1.
The vibration equations and finite element analysis model of the curved pipes conveying fluid are constructed and the dynamics of curved pipes under the boundary conditions of cantilever pipe are investigated also.
针对悬臂的边界条件,建立了在流体作用下输液曲管的振动方程及有限元分析模型,并研究了曲管的振动特性。
2.
Analyzing the stability of curved pipes conveying fluid by high precise direct integration method (HPD) is a new attempt.

6)  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。

依依杨柳，青丝缕、掩映绿波南浦。燕掠横斜，鳞游荡漾，恰是湔裙时序。清泠如许。恍镜影空磨，簟痕密聚。欲问伊人，且自溯洄前渚。并倚木阑无语。到来还、远树遥山，凝眸同睹。雁齿参差，＊流逦迤，多少鸥群鸳侣。最饶闲趣。且酒斟绿蚁，玉杯时举。＊乃一声，移入柳阴深处。西半夜惊罗一首，乃黄 词。 眼儿媚萧萧江上荻花秋一首，乃张孝祥词。堞恋花越女采莲秋水畔一首，乃欧阳修词。相见欢无言独上西楼一首，
