DIFFRACTION OF WATER WAVES BY A SUBMERGED CIRCULAR CYLINDER

The author discusses the physical phenomenon which occurs when a train of regular harmonic waves passes over a submerged circular cylinder. A discrepancy between the theoretical and experimental results is found when the cylinder is close to the water surface. The linearized potential theory gives a good description of the phenomenon in case the cylinder is well submerged. The phase angle between the incident waves and transmitted waves is found to be very sensitive with respect to the change of incident-wave slope. This effect may be related to the change of the proportion of the energy propagation that passed over the top and below the cylinder. A further study of this effect is recommended.
