ALAQS- CFD Comparison of Buoyant Free and Wall Turbulent Jets
This report investigates the effects of a solid boundary on the flow properties of a buoyant jet. A comparison was made with the results of a previous ALAQS report on an unbounded jet to highlight the difference jet behaviours. It is believed that the inclusion of the wall represents a further step towards a better understanding of the source dynamics behind an airplane jet engine during the ta...
متن کاملImpact of density differences on turbulent round jets
Jets with different density than the fluid into which they are issued, constitute an important class of flows relevant for applications in technical and environmental situations. In this work three cases of variable-density turbulent round jets discharging from a straight circular pipe into a weakly confined low-speed co-flowing air stream are studied with the aid of large eddy simulation. The ...
متن کاملPrimary Breakup of Turbulent Round Liquid Jets in Uniform Crossflows
Anexperimental investigation of the deformation andbreakupproperties of turbulent round liquid jets in uniform gaseous crossflows is described. Pulsed shadowgraphandholographobservationswere obtained for turbulent round liquid jets injected normal to air crossflow in a shock tube. Crossflow velocities of the air behind the shock wave relative to the liquid jet were subsonic (36–90 m=s) and the ...
متن کاملDirect numerical simulation of round turbulent jets in crossflow
Direct numerical simulation is used to study a round turbulent jet in a laminar crossflow. The ratio of bulk jet velocity to free-stream crossflow velocity is 5.7 and the Reynolds number based on the bulk jet velocity and the jet exit diameter is 5000. The mean velocity and turbulent intensities from the simulations are compared to data from the experiments by Su & Mungal (2004) and good agreem...
متن کاملEntrainment Characteristics of Turbulent Round Gas Jets Submerged in Water
The entrainment process in two-phase buoyant jets differs significantly from their singlephase counterparts, and is not well understood. Entrainment models developed for singlephase flow are often used in two-phase jetting simulations, albeit with limited success. In this work, Particle Image Velocimetry (PIV) and shadowgraph flow visualization experiments have been conducted on submerged round...
