A decade ago, Couder and Fort [Phys. Rev. Lett. 97, 154101 (2006)] discovered that a millimetric droplet sustained on the surface of a vibrating fluid bath may self-propel through a resonant interaction with its own wave field. We here present the results of a combined experimental and theoretical investigation of the interactions of such walking droplets. Specifically, we delimit experimentall...

This paper presents a numerical model for the simulation of solitary wave transformation around a permeable submerged breakwater. The wave-structure interaction is obtained by solving the Volume-Averaged Reynolds-Averaged Navier-Stokes governing equations VARANS and volume of fluid VOF theory. This model is applied to understand the effects of porosity, equivalent mean diameter of porous media,...

In this paper, the reflection and refraction of longitudinal wave from a plane surface separating a micropolar viscoelastic solid half space and a fluid saturated incompressible half space is studied. A longitudinal wave (P-wave) impinges obliquely at the interface. Amplitude ratios for various reflected and transmitted waves have been obtained. Then these amplitude ratios have been computed nu...

675 Theory of spatially periodic progressive (propagat ing with constant velocity without change of the amplitude) waves in two dimensional (2D) potential flow of an ideal incompressible fluid with free surface in gravitational field was founded in pioneering works by Stokes [1, 2] and developed further by Michell [3], Nekrasov [4, 5], and many others (see, e.g., book [6] by Sretenskii for revi...

Ocean waves move due to gravity: the water at crests is heavier than the air surrounding it and so it falls, overshoots its equilibrium position and then at a trough feels an upward restoring force. The same phenomena occurs below the ocean surface. Cold water lifted upward into warmer surroundings will feel a downward buoyancy force and downwarddisplaced warm water will feel an upward buoyancy...
