Summary
Trajectories in the turbulent boundary layer have been computed using a dynamic model, for a separating and a nonseparating case. The turbulent kinetic energy, the eddy diffusion coefficient and the hill factor have been evaluated along the trajectories, to get some insight into the different dispersion properties of such flows.
Riassunto
Sono state calcolate le traiettorie in uno strato limite turbolento utilizzando un modello dinamico, sia per un caso con separazione, sia per un caso senza separazione. Lungo le traiettorie sono stati valutati l'energia cinetica turbolenta, il coefficiente di diffusione turbolento ed il cosiddetto “hill factor”, per avere alcune indicazioni sulle differenti proprietà dispersive di questi flussi.
