    Turbulent Jets SUMMARY: This chapter is concerned with turbulent jets, namely their overall shape and velocity structure. The first jets being considered are those penetrating in homogeneous fluids, and the theory is later extended to consider the effects of a cross-current and of ambient buoyancy.

An experimental investigation of the effects of Reynolds number and Richardson number on the structure of a co-flowing buoyant jet. SUDAAR Stanford University, Department of Aeronautics and by:

    An experimental study was made of the variation of volume and centerline dilution as a function of Reynolds number in non-buoyant and buoyant round jets discharged vertically from a submerged nozzle. Measurements of jet temperature profiles are obtained by . Besides the experimental research, mathematical modelling of negatively buoyant jets has also received considerable attention. Application of commercial software packages which have been originally developed for positively buoyant jets has shown limited success so far, as reviewed by Palomar et al [12]. This is due to.

    The computed jet trajectories of the submerged offset jet show a satisfactory agreement with the experimental data. Keywords: offset jet, coanda effect, rough bed, recirculation region, open channel flow, boundary layer. 1. INTRODUCTION. The topic of submerged wall jets has been the focus of many investigators due to their engineering Author: Galla Ravi Kishore, Subhasish Dey. Numerous studies indicate that the jet-induced effect is an important characteristic in submerged gas jet process. For example, Dai et al described an experimental investigation of the flow pattern and hydrodynamic effect of underwater gas jets from supersonic and sonic nozzles operated in both perfect and imperfect expansion conditions.

The centre dilution, the trajectory and the turbulence structure of a plane buoyant jet issued horizontally are studied. It is found that the trajectory of a thermal water jet can be predicted reasonably well, provided that the conservation of heat flux, instead of buoyancy flux is : P.

The basic physical processes for a submerged turbulent buoyant jet released from sea outfall have been outlined and divided into four primary stages, namely, the zone of flow establishment, the stage of jet, the stage of intermediate and the stage of plume.

However, when it was time for the investigation of the buoyant jets with a three-dimensional path, all the knowledge that was gained from the flows with a two-dimensional path was applied in the design and analysis of that.The phenomenon of turbulent, buoyant jets in crossflow is a fundamental fluid mechanics problem with many application areas, including jets discharged from natural and mechanical draft cooling towers.

Buoyant jets were studied for many years, and as a result there exists a large body of literature on this and other related topics. An extensive review of this literature showed that there was a Author: Jim A. Leylek.
