Stereo-Piv Measurements of Flow at Boundary of Spur Dikes

Key Points

• This research aims to understand how momentum transport occurs at the boundary between main flow and spur dike areas.
• Utilized stereo-PIV (Particle Image Velocimetry) for flow measurement.
• Focused on the boundary region around 1-2 upstream spur dikes.
• Analyzed flow direction in three axes: x (downstream), y (crosswise), and z (vertical).
• Found that upward flow shows less contribution from turbulence compared to horizontal and downstream flows.
• Increased turbulence contribution was noted in x-z and y-z planes for upward flow.
• Indicated that the orientation of spur dikes affects turbulence structures.
