IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Large eddy simulations of 45กใ inclined dense jets

ABSTRACT
Submerged inclined dense jets (negatively buoyant jets) occur in many engineering applications such as brine discharges
from seawater desalination plants and de-cooling water discharges from liquefied natural gas (LNG) plants, and their
mixing behavior needs to be examined in details for the environmental impact analysis. In the present study, a detailed
numerical investigation was performed using the Large Eddy Simulations (LES) approach with both the Smagorinsky and
Dynamic Smagorinsky sub-grid scale (SGS) models to simulate the mixing characteristics of the inclined dense jet with a
45กใ inclination. The numerical predictions included the jet trajectory, geometrical characteristics and the dilution.
Experimental measurements were also obtained for the validation of the LES predictions, and data from existing studies in
the literature were included for comparison. Overall, the LES predictions were able to reproduce both the geometric
characteristics and dilution of the inclined dense jet in a satisfactory manner in most aspects.
