La turbulencia en canales abiertos. Un enfoque lagrangiano
[EN] Reynolds experiments demonstrated that, once a Reynolds number threshold is exceeded, water flow ceases to follow an orderly pattern with trajectories parallel to the contours and becomes chaotic.

| Sumario: | [EN] Reynolds experiments demonstrated that, once a Reynolds number threshold is exceeded, water flow ceases to follow an orderly pattern with trajectories parallel to the contours and becomes chaotic. Currently, turbulence has been described in numerical models using a theoretical approach, solving the turbulence closure problem. The Lagrangian description of fluid particle motion with the SPHERIMENTAL model is used to analyze the turbulent behavior of particles and to calculate the friction slope as a function of the path traveled. The results have been compared with the friction slope defined by Manning, providing a physical explanation for the traditional concept of friction slope. |
