THEORY FOR ARTICULATED DOUBLE-FLAP WAVE MAKERS IN WATER OF CONSTANT DEPTH

Extending the theoretical work of Biesel, a preliminary study is made of dynamic characteristics of an articulated double-flap wavemaker. The underlying motivation of utilizing a double-flap waveboard is based on its effectiveness in reducing the local disturbances in the immediate vicinity of the waveboard, which is demonstrated through decreasing inertia pressures. The additional degree of freedom in the double-flap waveboard movements is shown to be capable of encompassing a wider range of wavelength that can be satisfactorily generated in a given tank. The inertia pressure is reduced significantly by use of double-flap wavemakers, especially when short waves are generated. The usual wavemaker performance curves are computed for double-flap wavemakers. Comparison with the results of a single-flap wavemaker characteristics reveals that considerable improvement in performance curves is feasible by selecting a suitable combination of design parameters.
