A simple model of wave–current interaction

Journal of Fluid Mechanics, 2015
The interaction between a steady current and propagating surface waves is investigated by means of a perturbation approach, which assumes small values of the wave steepness and considers current velocities of the same order of magnitude as the amplitude of the velocity oscillations induced by wave propagation.

Interaction of Water Waves and Currents

1976
Publisher Summary This chapter discusses the varied physical circumstances in which interactions among water waves and currents occur. Different mathematical approaches, relevant observations, and experiments that are applicable to all or some of these physical circumstances are described.

Investigation into wave—current interactions in marine current turbines

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2007
The paper looks at the use of blade element-momentum theory for predicting the torque and thrust on a marine current turbine and the results of wave tank tests using a 400 mm-diameter rotor model. To include the effects of waves, linear wave theory particle velocities and accelerations were integrated into the mathematical model.

Interaction of Random Waves and Currents

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1985
The effects of steady, uniform currents on random waves, and the associated waterparticle kinematics, are investigated.

On the interaction between waves and currents

Ocean Engineering, 1990
Abstract The interaction of a current-free plane surface wave train of fixed frequency and a uniform wave-free current normal to the wave crests in the same or opposite direction to wave propagation is described. Neglecting dissipation, the combined field after the encounter is assumed stable, uniform, steady and irrotational.

Longshore Currents with Wave Current Interaction

Journal of the Waterway, Port, Coastal and Ocean Division, 1980
This note is intended to examine analytically the effects of larger angles of wave incidence and the refraction of the waves by the longshore current on planar beaches for the case of no lateral mixing.

Wave‐Tubular Member—Wave and Current Interaction

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1989
The in‐line hydrodynamic forces on submerged tubular members have been investigated experimentally for different positional depths (z/h), relative clearances (e/D), diameter‐to‐water depth ratios (D/h), and horizontal gap‐to‐diameter ratios (G/D). The forces due to wave‐current interaction on the tubular members near the free surface show an increase ...

Generation of short waves by wave-current interaction

IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2002
Measurements of blocking of gravity waves by inhomogeneous currents are presented. In the wave tank at the NASA Air-Sea Interaction Research Facility, Wallops Island, VA, mechanically-generated periodic waves (1-3 Hz) were blocked upstream from the wave paddle by an opposing current (20-45 cms/sup -1/).

Interaction of magnetostatic waves with a current

Journal of Applied Physics, 1978
It is shown that the interaction of magnetostatic waves with a current can be characterized by a coupling constant analogous to, but much greater than, the piezoelectric coupling constant. The theory is applied both to surface and forward-traveling volume magnetostatic waves, and the problems of excitation, reflection, and absorption by a single ...
