Wave motion in finite and infinite media using the Thin-Layer Method
… semi-analytical technique that is efficient for wave propagation problems involving partially heterogeneous media. While the method has been used widely for horizontally stratified media, e.g. dynamic response of foundations over layered soils, there remain many unexplored aspects. These include …

On the application of finite element analysis to wave motion in one-dimensional waveguides
… issues concerning the application of the wave finite element (WFE) method to the free and forced vibrations of one-dimensional waveguides. A short section of the waveguide is modelled using conventional finite element (FE) methods. A periodicity condition is applied and the resulting mass …

An experimental investigation of unsteady separation shock wave motion in a plume-induced, separated flowfield
… investigation of the unsteady separation shock wave motion in plume-induced, boundary layer separated (PIBLS) flowfields has been conducted. The PIBLS flowfields were created in a blowdown-type wind tunnel designed specifically to produce PIBLS in a planar, two-stream, supersonic flow. In this …

Modeling Bubble Coarsening in Froth Phase from First Principles
… to control the film drainage rate and affect the waves motions at the air/water interfaces. If the disjoining pressure is negative, both the film drainage and the capillary wave motion accelerate. When the TLF thins to a critical film thickness (Hcr), the amplitude of the wave motion grows …

Non-linear propagation of waves on two-dimensional liquid sheets
… behavior of antisymmetric as well as symmetric waves on a two-dimensional liquid sheet is studied, the effects of the surrounding fluid being taken into account. The non-linear Schrödinger equation governing the wave motion is derived by the method of multiple scales. Modulatory stability, …

Experimental visualization of the near-boundary hydrodynamics about fish-like swimming bodies
… fish were investigated. How the undulating motion of the boundary controls both the turbulence production and the boundary layer development is of great interest. Unsteady motions have been shown effective in controlling flow. Tokumaru and Dimotakis (1991) demonstrated the control of vortex …
