Abstract

The kinetics of flow around submarine pipeline with spoiler is studied by lattice Boltzmann method. The pipeline is half buried in the seabed. The existence of spoiler not only increases the contact pressure difference along seabed surface, but also leads to additional torque acting on the pipeline center. The latter has certain potential safety hazard to pipeline. Present study gives torque level under different spoiler height and the corresponding mechanism is illustrated.
