#structural turbulence
- Whirlpool — A circular and turbulent movement of a fluid, primarily encountered in hydrography as a powerful water whirlpool forming in rivers, in areas where the main current strikes an obstacle, a bend in the bank, or undergoes a sudden shift in depth. This structural hydrodynamic phenomenon creates a downward suction zone dangerous for navigation and swimming, generated by the intersection of water filaments with different speeds and directions.
