Hydrodynamic Forces on Partly Buried Pipelines in Waves/Current

摘要

In this study, the forces on a cylinder, laid on, or partly buried in the sea bed, were determined by measuring the pressure distribution on the cylinder surface in the case of steady current, pure wave and combined waves and current. Force coefficients were obtained for the ranges of Re = 0.8 - 2xl0~4, KC = 1-10, the current-to wave-velocity ratio = 0;3;6; and infinity (current) and for the burial-depth-to-the diameter ratio = 0-0.7.
