The Effect of Porous Plate on Surface Waves

Li Wei; Wang Jinjun  
The linearized porous wave maker theory presented by Chwang [1] was applied to obtain the free surface wave profiles produced by vertical non-porous end plate and vertical porous plate in the vicinity of the end plate both or only one of them doing small amplitude piston type movement in a semi infinite constant depth channel. The influence of the dimensionless porous effect parameter G on wave profile is studied, when the dimensionless wave effect parmeter is a constant. It is found that when the distance between the two plates is a multiple of the half-wavelength of propagating surface waves, the "wave-trapping" phenomenon and "wave-invariability" phenomenon will occur. The possible resonances are discussed. And the experiment is done to verify the theory.
