Abstrakt

The mean behaviour of horizontal turbulent buoyant jets in co-flowing currents is investigated experimentally and numerically, in terms of jet trajectory, dilution and centerline density deficit and velocity decay. It is demonstrated in the paper that the laboratory data on the jet trajectory and dilution can be successfully correlated by use of momentum or buoyancy length scales. In addition the centerline density deficit and velocity decay are well predicted by using an integral and a k - ∈turbulence model. The results shown here help us to understand in a better way the physical phenornenon of turbulent buoyant jet in the presence of arnbient current and provide a ready tool for the purpose of sea outfall design.
