Solitary wave interacting with two cylinders: A mixing process
A solitary wave is sent from left side of the flume. The flume is 0.6m wide with 0.2m still water depth. The solitary wave then interacts with a two-cylinder structure. Numerical dye is sitting on top of the two-cylinder structure to visualize and trace the mixing process. An unstructured mesh and downstream convective open boundary condition are adopted.

The white indicates the two-cylinder structure. The arrows indicate the velocity vectors on the center cross-section, and the red is the numerical dye. The yellow and blue are the vorticities of the y (lateral direction) component.
