摘要

在本文中,我们研究了浸没在海洋中并与垂线倾斜一定角度的多孔板对水波的散射问题。这个问题是用第二类超奇异积分方程来表示的。然后用切比切夫多项式表示未知函数,采用配置法求解超奇异积分方程。然后得到反射系数和透射系数,并用图形表示。观察到,板的孔隙度耗散了波能,从而减少了波能的反射和透射。然而,发现冰盖的存在减少了能量的耗散,也减少了波能的反射,从而增加了波能的透射。多孔板倾斜角度的增大减小了波的反射和能量的耗散。

Scattering of water waves by an inclined porous plate submerged in ocean with ice cover
In the present article, we have studied the problem of scattering of water waves by a porous plate submerged in the ocean and inclined at an angle to the vertical. The problem is formulated in terms of a hypersingular integral equation of the second kind. The hypersingular integral equation is then solved by a collocation method by representing the unknown function using Tchebychev polynomials. The reflection and transmission coefficients are then obtained and presented graphically. It is observed that porosity of the plate dissipates the wave energy and thereby reduces the reflection and transmission of wave energy. However, it is found that the presence of ice cover reduces the dissipation of energy and also the reflection of wave energy and thereby increases the transmission of wave energy. Also, the increase in angle of inclination of porous plate reduces the energy dissipation as well as the reflection of waves.
