Abstract:
This study aims to clarify the influence of Reynolds number on the growth behavior and structural stability of turbulence-induced gels formed by dosing a surfactant solution through a permeable wall in an open-channel turbulent flow. Experiments were conducted under two Reynolds number conditions with different turbulence intensities. Using video imaging and image analysis, the gel’s growth and height fluctuations were visualized and quantified. The results showed that under higher Reynolds number conditions, the gel grew faster, extended more significantly, and exhibited larger fluctuations. These findings indicate that turbulence strength plays a critical role in the formation and dynamic behavior of the gel structure.
