在沿岸流作用下的线性短峰波解析解

Linear analytical solution for longshore currents on short-crested waves

由于目前三维短峰波的研究甚少涉及普遍的波-流相互作用机制,为此,针对波浪倾斜入射岸堤、反射、并伴随强烈沿岸流作用的典型近海波况,构造出有限水深短峰波一般线性系统,并得到其一般解析解和特定的深水、浅水波解析解。从而,进一步完善了现有的线性水波理论体系,为非线性短峰波理论在波-流相互作用领域里的探讨提供了一个可靠基础。

The linear solution always plays a leading role in theory construction. As the present studies on the short-crested waves are involved in the wide wave-current interactions, considering a typical coastal wave condition concerning both obliquely incident waves on and reflected ones tern on finite depth short-crested waves low waters are acquired only to improve of the nonlinear short-crested waves on coast barriers with the strong longshore current influence, a general linear syseveloped, and the general solution and the special ones in both the deep and shalexisting linear water wave system and providing a reliable base for the investigations wave-current interactions
