Abstract This study determines the natural frequencies of the lock gate structure,
considering the coupled effect of reservoir fluid on one side using the finite element method (FEM). The gate is assumed to be a uniformly thick plate, and its
material is isotropic, homogeneous, and elastic. The reservoir fluid is assumed
to be inviscid and incompressible in an irrotational flow field. The length of the
reservoir domain is truncated using the far boundary condition by adopting the
Fourier series expansion theory. Two different assumptions on the free surface,
i.e., undisturbed and linearized, are considered in the… More >
