Investigation of Single and Multiple Solitary Waves Using Superresolution PIV
Measurements of the characteristics of a solitary wave propagating alone or against a current were performed using superresolution particle image velocimetry (PIV). The velocity field was obtained when the solitary wave passed in front of a high-speed charged-coupled device camera. The instantaneous and spatial surface profiles were measured using four resistance wave gauges and the particle mask correlation method that was applied to monitor tracers seeded into the flow field. In addition, an algorithm was employed to track water particle paths in a two-dimensional scheme. The trajectory measured using the superresolution PIV was compared with the one modeled using the solitary wave theory. This flow visualization technique was applied to analyze the collision of two solitary waves propagating in the same and in opposite directions.
