Time Scale of Local Scour around Pipelines in Current, Waves, and Combined Waves and Current

Journal of Hydraulic Engineering, 2017
AbstractThis paper presents results of an experimental investigation into the time scale of local scour around subsea pipelines in current-only, wave-only, and combined wave and current flow condit...

The vertical structure of combined wave–current flow

Ocean Engineering, 2008
Abstract A simple numerical model, based on the Reynolds stress equations and k – e turbulence closure scheme, is developed for the coastal wave and current bottom boundary layer. The current friction velocity is introduced to account for the effect of currents on waves. The implicit Crank–Nicolson finite difference method discretizes the governing

Combined effects of current and waves on fluid force

Ocean Engineering, 1973
Abstract Combined effects of current and waves on the force exerted on an element of a cylinder in a random gravity wave field in deep water are studied. Wave-current interactions are taken into account. Statistical quantities of the fluid force such as force spectrum and root mean square value of the force are obtained numerically and presented in ...

Velocity distributions of waves and currents in the combined flow

Coastal Engineering, 1991
Abstract The theoretical model presented here is designed to predict waves and currents velocity profiles in the combined wave and current motion near a fixed bed. It is also valid for the pure wave motion, because the pure wave motion is only a special case of the combined flow.

Velocity distribution in combined wave–current flows

Advances in Water Resources, 2006
Abstract This paper investigates why the measured velocity profiles in combined wave–current flows deviate from the log-law. Most of previous researchers attributed the velocity deviation to the wave Reynolds stress— ρ u ˜ v ˜ ¯ only. However, this study shows that both the wave Reynolds stress and the momentum u
