Key Points

This research investigates how boundary confinement influences the wake dynamics of a circular cylinder in open channel flow.
Conducted complementary experiments alongside high-fidelity simulations.
Analyzed different boundary configurations and their impact on flow behavior.
Examined multiscale dynamics for cylinders positioned near a free surface.
Identified significant variations in instantaneous bed shear stress for cylinders near the wall.
Revealed differing flow patterns across various boundary configurations.
Documented unique wake dynamics depending on cylinder positioning relative to the boundary.

Implication

Complementary experiments and simulations show varying flow patterns due to boundary effects.

Abstract

• Boundary effects on wake dynamics. • Complementary experiment and high-fidelity simulations. • Differing flow patterns for each configuration explained. • Multiscale dynamics for cylinder near a free surface. • Significant variation of instantaneous bed shear stress for cylinder near the wall.
