... the submarine pipeline lies in the seabed firstly, pipeline and seabed contact with each other forceless. So there is only a line contact state between each other. When the pipeline is loaded by gravity or any other load, both pipe and soil deform near the contact line. Then a limited contact area is generated...

... with various swimming speeds ranging from 0.5m/s to 4.5m/s. The drag coefficient and the lift coefficient of the manta ray are measured and compared. Results show obvious differences between negative and positive angles of attack. Additionally, the deformation of the free surface induced by the gliding manta...
