Laboratory and Numerical Experiments on the Dilution of Buoyant Surface Plumes, result of a buoyancy-dependent spread and a vertical turbulent mixing, induced by bed friction and attenuated by the presence of a stable density gradient. It is concluded that the numerical model compares well with the measured data.

,Numerical Modelling of Jets and Plumes — A Civil Engineering Perspective,ntegral method to the general 3-dimensional solution of the Navier-Stokes equations. Also the predictive capabilities of the models are discussed. The presentation takes the perspective of civil engineering and covers issues like sewage outfalls and cooling water discharges to the sea.

The Effect of Ambient Turbulence on Jet Mixing,to the jet mixing process. Any justification for this approach is based on a very limited data set. This study considers the effect of ambient turbulence on the mixing of a nonbuoyant co-flowing jet. Existing models are reviewed to determine which one best reproduces observations in ambient fluids w

Behaviour of a Buoyant Surface Jet in a Crossflow,. From an engineering point of view, the trajectory of the jet, as well as the temperature or concentration fields, are usually the most relevant aspects. In this paper, experimental results are analysed, leading to the proposal of semi-empirical solutions for the case of a jet in a crossflow.

A Discrete Vortex Model of a 2-D Turbulent Jet,uces the formation of large-scale coherent structures, but the vortices tend to accumulate in the simulation. This can be overcome by adding a small co-flowing velocity. The profiles of mean velocities agree reasonably well with those predicted by an eddy viscosity model, although the centreline vel
