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

这项研究开发了一种预测水中超长管道运动的方法，该管道用于将化石燃料资源从海底输送到海洋表面。管道的运动有时会导致管道坍塌。该方法对考虑运动的管道设计具有一定的参考价值。此外，本研究还考察了小凸块的附着对减小运动的影响，结果表明，附着物可以增强运动，这取决于凸起附着的管道的位置。

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.
