چکیده
The interaction between an oceanic internal solitary wave (ISW) and a prototype submerged floating tunnel (SFT) is numerically investigated. Effect of amplitude, the relative distance SFT to pycnocline, cross-sectional geometry SFT, density ratio two fluid layers are analyzed. At potential application site, dynamic response composed tube-joint-mooring system forced by ISW studied using Finite Element Method (FEM) modeling. numerical results show that ISW-induced force can be effectively reduced adopting parametric cross section instead circle or ellipse. influence pycnocline crucial, remarkably alter vertical buoyancy-weight (BWR) during propagation. Large shear forces bending moments on occur, affecting tension in mooring lines, threatening safety reliability system. However, deflections accelerations under applied within structural serviceability requirements due low frequency compared natural tube.

Shoaling internal solitary waves
[1] The evolution and breaking of internal solitary waves in a shallow upper layer as they approach a constant bottom slope is examined through laboratory experiments. The waves are launched in a two-layer fluid through the standard lock-release method. In most experiments, the wave amplitude is significantly larger than the depth of the shallow upper layer so that they are not well described b...
متن کاملInternal Solitary Waves
The basic theory of internal solitary waves is reviewed, with the main emphasis on applications to the many observations of such waves in shallow coastal seas, fjords, lakes and in the atmospheric boundary layer. Commencing with the equations of motion for an inviscid, incompressible density-stratified fluid, we describe asymptotic reductions to model long-wave equations, including the well-kno...
متن کاملAtmospheric Internal Solitary Waves
The solitary waves that have been observed in the atmosphere fall broadly into two classes: those that propagate in a fairly shallow stratified layer near the ground and those that occupy the entire troposphere. We present a survey of the observations of both types of solitary waves. The generation mechanisms differ substantially for these two types of solitary waves. Those that propagate in a ...
متن کاملReview of Internal Solitary Waves
A variety of waves can be generated in the region between two fluids of different densities. These so called internal waves are dispersive and nonlinear even for modest amplitudes. This paper provides an review of various models (from weakly to fully nonlinear) of internal waves in the density-stratified flows. The properties of these waves as well as the processes of generation, interaction an...
