AN EXPERIMENTAL STUDY OF WIND-WAVE INTERACTIONS.
Abstract
An experimental investigation was made to determine the ratio of the wave-supported shear stress, phi sub w; to the total shear stress on the water surface, phi sub o. The experimental conditions were designed to correspond to those required for the application of the viscous shear flow theory of wave generation proposed by Brooke Benjamin (1959) and Miles (1962b). The experiments were performed in a wind-wave tunnel, 48 x 3-1/2 x 2 feet, with a mean water depth of 1-1/2 feet. The wind in the 6 in. air space above the water was fully-developed turbulent channel flow. The mean center-line wind speed, U sub xi, was kept constant at 1.20 m/s during all measurements made with the wind blowing over the water. An artificially generated, single-component, wave train of small amplitude provided a known, initial perturbation of the water surface with which the wind could interact. The range of wave frequencies investigated was from 4.0 to 5.2 cps. Wave measurements were made with capacitance wave probes, wind measurements with hot-wire anemometers. (Author)
