In the present study, a semi-analytical model based on small-amplitude wave theory is developed to describe fields around single gravity-type cylindrical open fish net cage. The cage may be submerged different depths below free-water surface. modelled as flexible porous membrane, and deflection of chamber expressed by transverse vibration equation strings. velocity potential expanded in form Fo...

The Venus flytrap (Dionaea muscipula) possesses an active trapping mechanism to capture insects with one of the most rapid movements in the plant kingdom, as described by Darwin. This article presents a detailed experimental investigation of trap closure by mechanical and electrical stimuli and the mechanism of this process. Trap closure consists of three distinctive phases: a silent phase with...

The hydroelastic interaction between an underwater explosion and an elastic plate is investigated num- erically through a domain-decomposition strategy. The three-dimensional features of the problem require a large computational effort, which is reduced through a weak coupling between a one-dimensional radial blast solver, which resolves the blast evolution far from the boundaries, and a three-...

The paper concerns the modelling of very large pontoon-type floating structures by thin beams and plates of shallow draft, excited by regular waves. It is shown how the classical theory of hydroelasticity, involving the concepts of added mass and damping associated with the structural responses, may be reconciled with more recent formulations. In the latter, coupled equations for displacement a...

A well-posedness theory for the initial value problem for hydroelastic waves in two spatial dimensions is presented. This problem, which arises in numerous applications, describes the evolution of a thin elastic membrane in a two-dimensional potential flow. We use a model for the elastic sheet that accounts for bending stresses and membrane tension, but which neglects the mass of the membrane. ...

With the increase of ship size, stiffness hull structure becomes smaller. This means that frequency wave excitation tends to be closer natural vibration, which in turn makes hydroelastic responses more significant. An accurate assessment loads and motion hulls is key design safety assessment. In this paper, coupled CFD (Computational Fluid Dynamics)-FEM (Finite Element Method) method used inves...
