Abstract

The vortex structure induced by a solitary wave propagating over a rectangular cavity is studied experimentally, using the particle image velocimetry (PIV) and flow visualization technique. The aspect ratio of the cavity (the ratio of length to depth of a cavity, G/D) ranges from 0.33 to infinity in the study. The ratio of wave height (H) to water depth (D) in the experiment is 0.2. The vortex shedding process was identified particularly for G/D = 1.0. Detailed vortical structures in the case were observed using flow visualization technique - particle trajectory photography. The quantitative characteristics of shedding primary vortex in the cavity, such as the trajectories of the vortex core, vorticity of the primary vortex core, and the circulation of the primary vortex, are discussed in detail.
