説明
A feasibility study is to done make an advancing wave system with a simple component of wavenumber on the water surface of a circulating water channel by making the wave-suppressor-plate oscillate at the top of the outlet of the channel. At first using the 2-D linearized theory for an oscillating planing plate the wave-making characteristics of the heaving and pitching motion of the suppressor are analyzed numerically. From these characteristics wave-free conditon except for only one component of advancing wave system is obtained and the calculated results under such a condition show an ability of suppressor-plate type of wave-maker for a circulating water channel. Next experimental apparatus is made to make the suppressor-plate heave(not pitch)and the generated waves are measured with two methods, image analyzing method for some instantaneous wave configurations in a period time taken by high-speed video camera and wave-height-gauge method for time sequential wave records at some positions between a half beat length. The experimental results coincides with the calculated characteristics except in the cases at lower stream velocities due to the higher ratio of wave height by length and at higher frequencies due to the lower performance of the servo type of wave gauge. From the theoretical and experimental results it is concluded that the suppressor-plate type of wave-maker can be realized when it is controlled in a given mode of combination of heaving and pitching motions.
