Development of simulation method for fluid-structure interaction of catenary shaped-riser pipe.

这项研究开发了一种方法来预测一个很长的管道在水中，这是用来输送化石燃料资源从海底到海洋表面的运动。管道的运动偶尔会导致管道塌陷。该方法对考虑管道运动的管道设计具有一定的参考价值。并且，本研究检查了小凸起的附着对减少运动的影响，并且表明附着可以根据凸起附着的管道的位置来增强运动。

This study developed a method for predicting the motion of a very long pipe in water, which is used to convey fossil fuels resource from sea floor to the surface of the ocean. The motion of the pipe can occasionally cause collapse of the pipe. This method is useful to design the pipe considering the motion. And, this study examined the effect of attachment of small bumps on the reduction of the motion, and showed that the attachment can enhance the motion depending on position of the pipe where the bumps are attached.
