Abstract
In this study, the characteristics of a round turbulent jet in the vicinity of a free surface are investigated. The results reveal that the velocity normal to the free surface is diminished, and the velocity components parallel to the free surface are enhanced in the region near the free surface. The magnitude of shear stress in the vertical central plane of the surface jet is smaller than that noticed in the free jet near the free surface, while the magnitudes of profiles are larger compared to that of the free jet. A higher magnitude of the vorticity is observed in the shear layers of the surface jet compared to that of the free jet. It is also noticed that the large-scale flow contributes the majority of streamwise turbulence intensity as well as shear stress, while the small-scale flow dominates the contribution of lateral turbulence intensity.
